Given numbers are 690, 432, 928, 681

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

Prime factors of 681 are 3 x 227

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

Given numbers are 690, 432, 928, 681

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

Apply this formula for all numbers.

Step1:

LCM(690, 432) = 49680

GCD(690, 432) = ( 690 x 432 ) / 49680

= 690 / 432

= 690

Step2:

LCM(6, 928) = 2784

GCD(6, 928) = ( 6 x 928 ) / 2784

= 6 / 928

= 6

Step3:

LCM(2, 681) = 1362

GCD(2, 681) = ( 2 x 681 ) / 1362

= 2 / 681

= 2

So, Greatest Common Divisor of 690, 432, 928, 681 is 1
