Given numbers are 970, 780, 427, 121

The list of prime factors of all numbers are

Prime factors of 970 are 2 x 5 x 97

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 427 are 7 x 61

Prime factors of 121 are 11 x 11

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

Given numbers are 970, 780, 427, 121

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

Apply this formula for all numbers.

Step1:

LCM(970, 780) = 75660

GCD(970, 780) = ( 970 x 780 ) / 75660

= 970 / 780

= 970

Step2:

LCM(10, 427) = 4270

GCD(10, 427) = ( 10 x 427 ) / 4270

= 10 / 427

= 10

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 970, 780, 427, 121 is 1
