Given numbers are 780, 108, 86, 437

The list of prime factors of all numbers are

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

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

Prime factors of 86 are 2 x 43

Prime factors of 437 are 19 x 23

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

Given numbers are 780, 108, 86, 437

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

Apply this formula for all numbers.

Step1:

LCM(780, 108) = 7020

GCD(780, 108) = ( 780 x 108 ) / 7020

= 780 / 108

= 780

Step2:

LCM(12, 86) = 516

GCD(12, 86) = ( 12 x 86 ) / 516

= 12 / 86

= 12

Step3:

LCM(2, 437) = 874

GCD(2, 437) = ( 2 x 437 ) / 874

= 2 / 437

= 2

So, Greatest Common Divisor of 780, 108, 86, 437 is 1
