Given numbers are 674, 869, 985, 780

The list of prime factors of all numbers are

Prime factors of 674 are 2 x 337

Prime factors of 869 are 11 x 79

Prime factors of 985 are 5 x 197

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

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

Given numbers are 674, 869, 985, 780

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

Apply this formula for all numbers.

Step1:

LCM(674, 869) = 585706

GCD(674, 869) = ( 674 x 869 ) / 585706

= 674 / 869

= 674

Step2:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 674, 869, 985, 780 is 1
