Given numbers are 644, 975, 486, 101

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

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

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 101 are 101

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

Given numbers are 644, 975, 486, 101

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

Apply this formula for all numbers.

Step1:

LCM(644, 975) = 627900

GCD(644, 975) = ( 644 x 975 ) / 627900

= 644 / 975

= 644

Step2:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

Step3:

LCM(1, 101) = 101

GCD(1, 101) = ( 1 x 101 ) / 101

= 1 / 101

= 1

So, Greatest Common Divisor of 644, 975, 486, 101 is 1
