Lcm Of 6 And 5

LCM of 5, 6, and 7

LCM of 5, 6, and 7 is the smallest number amongst all mutual multiples of 5, six, and 7. The beginning few multiples of v, half dozen, and 7 are (5, x, 15, 20, 25 . . .), (6, 12, xviii, 24, thirty . . .), and (7, fourteen, 21, 28, 35 . . .) respectively. There are 3 unremarkably used methods to detect LCM of five, vi, seven - past listing multiples, by sectionalisation method, and by prime factorization.

What is the LCM of five, vi, and 7?

Reply: LCM of 5, 6, and seven is 210.

Explanation:

The LCM of three non-aught integers, a(5), b(6), and c(7), is the smallest positive integer m(210) that is divisible by a(5), b(half-dozen), and c(seven) without whatever residuum.

Methods to Find LCM of 5, 6, and vii

The methods to find the LCM of 5, six, and seven are explained beneath.

• Past Prime Factorization Method
• By Segmentation Method
• By Listing Multiples

LCM of 5, 6, and 7 by Prime number Factorization

Prime factorization of v, 6, and 7 is (v) = 5¹, (2 × iii) = 2¹ × 3^ane, and (7) = 7¹ respectively. LCM of 5, 6, and 7 can be obtained past multiplying prime number factors raised to their respective highest power, i.eastward. two¹ × 3¹ × 5^ane × 7ⁱ = 210.
Hence, the LCM of five, 6, and vii by prime factorization is 210.

LCM of v, 6, and 7 by Division Method

To calculate the LCM of 5, 6, and vii by the sectionalisation method, nosotros will carve up the numbers(5, half dozen, 7) by their prime factors (preferably common). The production of these divisors gives the LCM of 5, half dozen, and vii.

• Footstep i: Find the smallest prime that is a factor of at least one of the numbers, five, half dozen, and seven. Write this prime number(ii) on the left of the given numbers(5, 6, and 7), separated equally per the ladder arrangement.
• Step 2: If any of the given numbers (5, half dozen, seven) is a multiple of two, dissever it past 2 and write the quotient below it. Bring down whatsoever number that is not divisible by the prime.
• Step 3: Go on the steps until only 1s are left in the last row.

The LCM of 5, vi, and 7 is the product of all prime numbers on the left, i.e. LCM(5, half-dozen, seven) by division method = two × 3 × 5 × 7 = 210.

LCM of 5, 6, and 7 by Listing Multiples

To calculate the LCM of 5, six, 7 by list out the mutual multiples, nosotros can follow the given below steps:

• Step 1: List a few multiples of 5 (5, ten, 15, 20, 25 . . .), 6 (6, 12, 18, 24, 30 . . .), and vii (seven, 14, 21, 28, 35 . . .).
• Pace 2: The common multiples from the multiples of 5, 6, and seven are 210, 420, . . .
• Step 3: The smallest common multiple of v, 6, and 7 is 210.

∴ The least common multiple of 5, 6, and vii = 210.
