Given numbers are 690, 325, 415, 921

The list of prime factors of all numbers are

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

Prime factors of 325 are 5 x 5 x 13

Prime factors of 415 are 5 x 83

Prime factors of 921 are 3 x 307

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

Given numbers are 690, 325, 415, 921

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

Apply this formula for all numbers.

Step1:

LCM(690, 325) = 44850

GCD(690, 325) = ( 690 x 325 ) / 44850

= 690 / 325

= 690

Step2:

LCM(5, 415) = 415

GCD(5, 415) = ( 5 x 415 ) / 415

= 5 / 415

= 5

Step3:

LCM(5, 921) = 4605

GCD(5, 921) = ( 5 x 921 ) / 4605

= 5 / 921

= 5

So, Greatest Common Divisor of 690, 325, 415, 921 is 1
