Given numbers are 620, 838, 666, 657

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 838 are 2 x 419

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 620, 838, 666, 657

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

Apply this formula for all numbers.

Step1:

LCM(620, 838) = 259780

GCD(620, 838) = ( 620 x 838 ) / 259780

= 620 / 838

= 620

Step2:

LCM(2, 666) = 666

GCD(2, 666) = ( 2 x 666 ) / 666

= 2 / 666

= 2

Step3:

LCM(2, 657) = 1314

GCD(2, 657) = ( 2 x 657 ) / 1314

= 2 / 657

= 2

So, Greatest Common Divisor of 620, 838, 666, 657 is 1
