Given numbers are 988, 675, 396, 780

The list of prime factors of all numbers are

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

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

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

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

Given numbers are 988, 675, 396, 780

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

Apply this formula for all numbers.

Step1:

LCM(988, 675) = 666900

GCD(988, 675) = ( 988 x 675 ) / 666900

= 988 / 675

= 988

Step2:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 988, 675, 396, 780 is 1
