Given numbers are 780, 612, 505, 955

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 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 505 are 5 x 101

Prime factors of 955 are 5 x 191

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

Given numbers are 780, 612, 505, 955

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

Apply this formula for all numbers.

Step1:

LCM(780, 612) = 39780

GCD(780, 612) = ( 780 x 612 ) / 39780

= 780 / 612

= 780

Step2:

LCM(12, 505) = 6060

GCD(12, 505) = ( 12 x 505 ) / 6060

= 12 / 505

= 12

Step3:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

So, Greatest Common Divisor of 780, 612, 505, 955 is 1
