Given numbers are 780, 112, 771, 570

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 112 are 2 x 2 x 2 x 2 x 7

Prime factors of 771 are 3 x 257

Prime factors of 570 are 2 x 3 x 5 x 19

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

Given numbers are 780, 112, 771, 570

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

Apply this formula for all numbers.

Step1:

LCM(780, 112) = 21840

GCD(780, 112) = ( 780 x 112 ) / 21840

= 780 / 112

= 780

Step2:

LCM(4, 771) = 3084

GCD(4, 771) = ( 4 x 771 ) / 3084

= 4 / 771

= 4

Step3:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 780, 112, 771, 570 is 1
