Given numbers are 644, 672, 844, 655

The list of prime factors of all numbers are

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

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 844 are 2 x 2 x 211

Prime factors of 655 are 5 x 131

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

Given numbers are 644, 672, 844, 655

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

Apply this formula for all numbers.

Step1:

LCM(644, 672) = 15456

GCD(644, 672) = ( 644 x 672 ) / 15456

= 644 / 672

= 644

Step2:

LCM(28, 844) = 5908

GCD(28, 844) = ( 28 x 844 ) / 5908

= 28 / 844

= 28

Step3:

LCM(4, 655) = 2620

GCD(4, 655) = ( 4 x 655 ) / 2620

= 4 / 655

= 4

So, Greatest Common Divisor of 644, 672, 844, 655 is 1
