Given numbers are 644, 501, 640, 895

The list of prime factors of all numbers are

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

Prime factors of 501 are 3 x 167

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 895 are 5 x 179

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

Given numbers are 644, 501, 640, 895

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

Apply this formula for all numbers.

Step1:

LCM(644, 501) = 322644

GCD(644, 501) = ( 644 x 501 ) / 322644

= 644 / 501

= 644

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 895) = 895

GCD(1, 895) = ( 1 x 895 ) / 895

= 1 / 895

= 1

So, Greatest Common Divisor of 644, 501, 640, 895 is 1
