Given numbers are 612, 855, 644, 470

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 855 are 3 x 3 x 5 x 19

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

Prime factors of 470 are 2 x 5 x 47

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

Given numbers are 612, 855, 644, 470

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

Apply this formula for all numbers.

Step1:

LCM(612, 855) = 58140

GCD(612, 855) = ( 612 x 855 ) / 58140

= 612 / 855

= 612

Step2:

LCM(9, 644) = 5796

GCD(9, 644) = ( 9 x 644 ) / 5796

= 9 / 644

= 9

Step3:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

So, Greatest Common Divisor of 612, 855, 644, 470 is 1
