Given numbers are 921, 818, 564, 660

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 818 are 2 x 409

Prime factors of 564 are 2 x 2 x 3 x 47

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

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

Given numbers are 921, 818, 564, 660

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

Apply this formula for all numbers.

Step1:

LCM(921, 818) = 753378

GCD(921, 818) = ( 921 x 818 ) / 753378

= 921 / 818

= 921

Step2:

LCM(1, 564) = 564

GCD(1, 564) = ( 1 x 564 ) / 564

= 1 / 564

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 921, 818, 564, 660 is 1
