Given numbers are 427, 990, 778, 507

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 778 are 2 x 389

Prime factors of 507 are 3 x 13 x 13

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

Given numbers are 427, 990, 778, 507

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

Apply this formula for all numbers.

Step1:

LCM(427, 990) = 422730

GCD(427, 990) = ( 427 x 990 ) / 422730

= 427 / 990

= 427

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

So, Greatest Common Divisor of 427, 990, 778, 507 is 1
