Given numbers are 974, 770, 392, 165

The list of prime factors of all numbers are

Prime factors of 974 are 2 x 487

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 974, 770, 392, 165

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

Apply this formula for all numbers.

Step1:

LCM(974, 770) = 374990

GCD(974, 770) = ( 974 x 770 ) / 374990

= 974 / 770

= 974

Step2:

LCM(2, 392) = 392

GCD(2, 392) = ( 2 x 392 ) / 392

= 2 / 392

= 2

Step3:

LCM(2, 165) = 330

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

= 2 / 165

= 2

So, Greatest Common Divisor of 974, 770, 392, 165 is 1
