Given numbers are 780, 782, 787, 630

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 782 are 2 x 17 x 23

Prime factors of 787 are 787

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 780, 782, 787, 630

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

Apply this formula for all numbers.

Step1:

LCM(780, 782) = 304980

GCD(780, 782) = ( 780 x 782 ) / 304980

= 780 / 782

= 780

Step2:

LCM(2, 787) = 1574

GCD(2, 787) = ( 2 x 787 ) / 1574

= 2 / 787

= 2

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 780, 782, 787, 630 is 1
