Given numbers are 450, 615, 347, 639

The list of prime factors of all numbers are

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 615 are 3 x 5 x 41

Prime factors of 347 are 347

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 450, 615, 347, 639

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

Apply this formula for all numbers.

Step1:

LCM(450, 615) = 18450

GCD(450, 615) = ( 450 x 615 ) / 18450

= 450 / 615

= 450

Step2:

LCM(15, 347) = 5205

GCD(15, 347) = ( 15 x 347 ) / 5205

= 15 / 347

= 15

Step3:

LCM(1, 639) = 639

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

= 1 / 639

= 1

So, Greatest Common Divisor of 450, 615, 347, 639 is 1
