Given numbers are 125, 780, 684, 419

The list of prime factors of all numbers are

Prime factors of 125 are 5 x 5 x 5

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

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 419 are 419

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

Given numbers are 125, 780, 684, 419

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

Apply this formula for all numbers.

Step1:

LCM(125, 780) = 19500

GCD(125, 780) = ( 125 x 780 ) / 19500

= 125 / 780

= 125

Step2:

LCM(5, 684) = 3420

GCD(5, 684) = ( 5 x 684 ) / 3420

= 5 / 684

= 5

Step3:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

So, Greatest Common Divisor of 125, 780, 684, 419 is 1
