Given numbers are 637, 162, 780, 403

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

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

Prime factors of 403 are 13 x 31

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

Given numbers are 637, 162, 780, 403

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

Apply this formula for all numbers.

Step1:

LCM(637, 162) = 103194

GCD(637, 162) = ( 637 x 162 ) / 103194

= 637 / 162

= 637

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 637, 162, 780, 403 is 1
