Given numbers are 310, 153, 639, 378

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 153 are 3 x 3 x 17

Prime factors of 639 are 3 x 3 x 71

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Given numbers are 310, 153, 639, 378

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

Apply this formula for all numbers.

Step1:

LCM(310, 153) = 47430

GCD(310, 153) = ( 310 x 153 ) / 47430

= 310 / 153

= 310

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 310, 153, 639, 378 is 1
