Given numbers are 921, 216, 628, 435

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 628 are 2 x 2 x 157

Prime factors of 435 are 3 x 5 x 29

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

Given numbers are 921, 216, 628, 435

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

Apply this formula for all numbers.

Step1:

LCM(921, 216) = 66312

GCD(921, 216) = ( 921 x 216 ) / 66312

= 921 / 216

= 921

Step2:

LCM(3, 628) = 1884

GCD(3, 628) = ( 3 x 628 ) / 1884

= 3 / 628

= 3

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 921, 216, 628, 435 is 1
