Given numbers are 921, 660, 470, 854

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 470 are 2 x 5 x 47

Prime factors of 854 are 2 x 7 x 61

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

Given numbers are 921, 660, 470, 854

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

Apply this formula for all numbers.

Step1:

LCM(921, 660) = 202620

GCD(921, 660) = ( 921 x 660 ) / 202620

= 921 / 660

= 921

Step2:

LCM(3, 470) = 1410

GCD(3, 470) = ( 3 x 470 ) / 1410

= 3 / 470

= 3

Step3:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

So, Greatest Common Divisor of 921, 660, 470, 854 is 1
