Given numbers are 780, 419, 903, 636

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 419 are 419

Prime factors of 903 are 3 x 7 x 43

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

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

Given numbers are 780, 419, 903, 636

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

Apply this formula for all numbers.

Step1:

LCM(780, 419) = 326820

GCD(780, 419) = ( 780 x 419 ) / 326820

= 780 / 419

= 780

Step2:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 780, 419, 903, 636 is 1
