Given numbers are 780, 857, 856, 377

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 857 are 857

Prime factors of 856 are 2 x 2 x 2 x 107

Prime factors of 377 are 13 x 29

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

Given numbers are 780, 857, 856, 377

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

Apply this formula for all numbers.

Step1:

LCM(780, 857) = 668460

GCD(780, 857) = ( 780 x 857 ) / 668460

= 780 / 857

= 780

Step2:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

Step3:

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

= 1 / 377

= 1

So, Greatest Common Divisor of 780, 857, 856, 377 is 1
