Given numbers are 771, 780, 552, 812

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 771, 780, 552, 812

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

Apply this formula for all numbers.

Step1:

LCM(771, 780) = 200460

GCD(771, 780) = ( 771 x 780 ) / 200460

= 771 / 780

= 771

Step2:

LCM(3, 552) = 552

GCD(3, 552) = ( 3 x 552 ) / 552

= 3 / 552

= 3

Step3:

LCM(3, 812) = 2436

GCD(3, 812) = ( 3 x 812 ) / 2436

= 3 / 812

= 3

So, Greatest Common Divisor of 771, 780, 552, 812 is 1
