Given numbers are 430, 895, 639, 440

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 895 are 5 x 179

Prime factors of 639 are 3 x 3 x 71

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 430, 895, 639, 440

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

Apply this formula for all numbers.

Step1:

LCM(430, 895) = 76970

GCD(430, 895) = ( 430 x 895 ) / 76970

= 430 / 895

= 430

Step2:

LCM(5, 639) = 3195

GCD(5, 639) = ( 5 x 639 ) / 3195

= 5 / 639

= 5

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 430, 895, 639, 440 is 1
