Given numbers are 780, 545, 636, 873

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 545 are 5 x 109

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 873 are 3 x 3 x 97

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

Given numbers are 780, 545, 636, 873

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

Apply this formula for all numbers.

Step1:

LCM(780, 545) = 85020

GCD(780, 545) = ( 780 x 545 ) / 85020

= 780 / 545

= 780

Step2:

LCM(5, 636) = 3180

GCD(5, 636) = ( 5 x 636 ) / 3180

= 5 / 636

= 5

Step3:

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

= 1 / 873

= 1

So, Greatest Common Divisor of 780, 545, 636, 873 is 1
