Given numbers are 639, 354, 690, 416

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 354 are 2 x 3 x 59

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

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

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

Given numbers are 639, 354, 690, 416

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

Apply this formula for all numbers.

Step1:

LCM(639, 354) = 75402

GCD(639, 354) = ( 639 x 354 ) / 75402

= 639 / 354

= 639

Step2:

LCM(3, 690) = 690

GCD(3, 690) = ( 3 x 690 ) / 690

= 3 / 690

= 3

Step3:

LCM(3, 416) = 1248

GCD(3, 416) = ( 3 x 416 ) / 1248

= 3 / 416

= 3

So, Greatest Common Divisor of 639, 354, 690, 416 is 1
