Given numbers are 780, 427, 988, 521

The list of prime factors of all numbers are

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

Prime factors of 427 are 7 x 61

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 521 are 521

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

Given numbers are 780, 427, 988, 521

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

Apply this formula for all numbers.

Step1:

LCM(780, 427) = 333060

GCD(780, 427) = ( 780 x 427 ) / 333060

= 780 / 427

= 780

Step2:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

Step3:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 780, 427, 988, 521 is 1
