Given numbers are 210, 272, 165, 974

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 165 are 3 x 5 x 11

Prime factors of 974 are 2 x 487

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 210, 272, 165, 974

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(210, 272) = 28560

GCD(210, 272) = ( 210 x 272 ) / 28560

= 210 / 272

= 210

Step2:

LCM(2, 165) = 330

GCD(2, 165) = ( 2 x 165 ) / 330

= 2 / 165

= 2

Step3:

LCM(1, 974) = 974

GCD(1, 974) = ( 1 x 974 ) / 974

= 1 / 974

= 1

So, Greatest Common Divisor of 210, 272, 165, 974 is 1
