Given numbers are 975, 648, 605, 430

The list of prime factors of all numbers are

Prime factors of 975 are 3 x 5 x 5 x 13

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 605 are 5 x 11 x 11

Prime factors of 430 are 2 x 5 x 43

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

Given numbers are 975, 648, 605, 430

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

Apply this formula for all numbers.

Step1:

LCM(975, 648) = 210600

GCD(975, 648) = ( 975 x 648 ) / 210600

= 975 / 648

= 975

Step2:

LCM(3, 605) = 1815

GCD(3, 605) = ( 3 x 605 ) / 1815

= 3 / 605

= 3

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 975, 648, 605, 430 is 1
