Given numbers are 904, 530, 646, 981

The list of prime factors of all numbers are

Prime factors of 904 are 2 x 2 x 2 x 113

Prime factors of 530 are 2 x 5 x 53

Prime factors of 646 are 2 x 17 x 19

Prime factors of 981 are 3 x 3 x 109

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

Given numbers are 904, 530, 646, 981

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

Apply this formula for all numbers.

Step1:

LCM(904, 530) = 239560

GCD(904, 530) = ( 904 x 530 ) / 239560

= 904 / 530

= 904

Step2:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

Step3:

LCM(2, 981) = 1962

GCD(2, 981) = ( 2 x 981 ) / 1962

= 2 / 981

= 2

So, Greatest Common Divisor of 904, 530, 646, 981 is 1
