Given numbers are 921, 720, 411, 694

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 411 are 3 x 137

Prime factors of 694 are 2 x 347

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

Given numbers are 921, 720, 411, 694

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

Apply this formula for all numbers.

Step1:

LCM(921, 720) = 221040

GCD(921, 720) = ( 921 x 720 ) / 221040

= 921 / 720

= 921

Step2:

LCM(3, 411) = 411

GCD(3, 411) = ( 3 x 411 ) / 411

= 3 / 411

= 3

Step3:

LCM(3, 694) = 2082

GCD(3, 694) = ( 3 x 694 ) / 2082

= 3 / 694

= 3

So, Greatest Common Divisor of 921, 720, 411, 694 is 1
