Given numbers are 102, 705, 639, 478

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

Prime factors of 705 are 3 x 5 x 47

Prime factors of 639 are 3 x 3 x 71

Prime factors of 478 are 2 x 239

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

Given numbers are 102, 705, 639, 478

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

Apply this formula for all numbers.

Step1:

LCM(102, 705) = 23970

GCD(102, 705) = ( 102 x 705 ) / 23970

= 102 / 705

= 102

Step2:

LCM(3, 639) = 639

GCD(3, 639) = ( 3 x 639 ) / 639

= 3 / 639

= 3

Step3:

LCM(3, 478) = 1434

GCD(3, 478) = ( 3 x 478 ) / 1434

= 3 / 478

= 3

So, Greatest Common Divisor of 102, 705, 639, 478 is 1
