Given numbers are 690, 386, 617, 677

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 386 are 2 x 193

Prime factors of 617 are 617

Prime factors of 677 are 677

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

Given numbers are 690, 386, 617, 677

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

Apply this formula for all numbers.

Step1:

LCM(690, 386) = 133170

GCD(690, 386) = ( 690 x 386 ) / 133170

= 690 / 386

= 690

Step2:

LCM(2, 617) = 1234

GCD(2, 617) = ( 2 x 617 ) / 1234

= 2 / 617

= 2

Step3:

LCM(1, 677) = 677

GCD(1, 677) = ( 1 x 677 ) / 677

= 1 / 677

= 1

So, Greatest Common Divisor of 690, 386, 617, 677 is 1
