Given numbers are 425, 105, 45, 634

The list of prime factors of all numbers are

Prime factors of 425 are 5 x 5 x 17

Prime factors of 105 are 3 x 5 x 7

Prime factors of 45 are 3 x 3 x 5

Prime factors of 634 are 2 x 317

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

Given numbers are 425, 105, 45, 634

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

Apply this formula for all numbers.

Step1:

LCM(425, 105) = 8925

GCD(425, 105) = ( 425 x 105 ) / 8925

= 425 / 105

= 425

Step2:

LCM(5, 45) = 45

GCD(5, 45) = ( 5 x 45 ) / 45

= 5 / 45

= 5

Step3:

LCM(5, 634) = 3170

GCD(5, 634) = ( 5 x 634 ) / 3170

= 5 / 634

= 5

So, Greatest Common Divisor of 425, 105, 45, 634 is 1
