Example 1: uncover the smallest number that is divisible through 5, 6, 7 exactly.

Solution:

The value of LCM(5, 6, 7) will be the smallest number that is specifically divisible by 5, 6, and 7.⇒ Multiples the 5, 6, and 7:

Multiples the 5 = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, . . . ., 200, 205, 210, . . . .Multiples the 6 = 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . . ., 192, 198, 204, 210, . . . .Multiples that 7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, . . . ., 189, 196, 203, 210, . . . .

Therefore, the LCM that 5, 6, and 7 is 210.


Example 2: Verify the relationship between the GCD and LCM the 5, 6, and also 7.

Solution:

The relation in between GCD and also LCM that 5, 6, and 7 is offered as,LCM(5, 6, 7) = <(5 × 6 × 7) × GCD(5, 6, 7)>/⇒ prime factorization the 5, 6 and also 7:

5 = 516 = 21 × 317 = 71

∴ GCD of (5, 6), (6, 7), (5, 7) and also (5, 6, 7) = 1, 1, 1 and also 1 respectively.Now, LHS = LCM(5, 6, 7) = 210.And, RHS = <(5 × 6 × 7) × GCD(5, 6, 7)>/ = <(210) × 1>/<1 × 1 × 1> = 210LHS = RHS = 210.Hence verified.


Example 3: calculate the LCM the 5, 6, and also 7 utilizing the GCD the the given numbers.

Solution:

Prime administrate of 5, 6, 7:

5 = 516 = 21 × 317 = 71

Therefore, GCD(5, 6) = 1, GCD(6, 7) = 1, GCD(5, 7) = 1, GCD(5, 6, 7) = 1We know,LCM(5, 6, 7) = <(5 × 6 × 7) × GCD(5, 6, 7)>/LCM(5, 6, 7) = (210 × 1)/(1 × 1 × 1) = 210⇒LCM(5, 6, 7) = 210
