Given numbers are 126, 872, 780, 515

The list of prime factors of all numbers are

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 872 are 2 x 2 x 2 x 109

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

Prime factors of 515 are 5 x 103

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

Given numbers are 126, 872, 780, 515

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

Apply this formula for all numbers.

Step1:

LCM(126, 872) = 54936

GCD(126, 872) = ( 126 x 872 ) / 54936

= 126 / 872

= 126

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

So, Greatest Common Divisor of 126, 872, 780, 515 is 1
