Given numbers are 521, 780, 890, 931

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 890 are 2 x 5 x 89

Prime factors of 931 are 7 x 7 x 19

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

Given numbers are 521, 780, 890, 931

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

Apply this formula for all numbers.

Step1:

LCM(521, 780) = 406380

GCD(521, 780) = ( 521 x 780 ) / 406380

= 521 / 780

= 521

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

Step3:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

So, Greatest Common Divisor of 521, 780, 890, 931 is 1
