Given numbers are 635, 780, 13, 480

The list of prime factors of all numbers are

Prime factors of 635 are 5 x 127

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

Prime factors of 13 are 13

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 635, 780, 13, 480

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

Apply this formula for all numbers.

Step1:

LCM(635, 780) = 99060

GCD(635, 780) = ( 635 x 780 ) / 99060

= 635 / 780

= 635

Step2:

LCM(5, 13) = 65

GCD(5, 13) = ( 5 x 13 ) / 65

= 5 / 13

= 5

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 635, 780, 13, 480 is 1
