Given numbers are 312, 648, 989, 672

The list of prime factors of all numbers are

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Prime factors of 989 are 23 x 43

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

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

Given numbers are 312, 648, 989, 672

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

Apply this formula for all numbers.

Step1:

LCM(312, 648) = 8424

GCD(312, 648) = ( 312 x 648 ) / 8424

= 312 / 648

= 312

Step2:

LCM(24, 989) = 23736

GCD(24, 989) = ( 24 x 989 ) / 23736

= 24 / 989

= 24

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 312, 648, 989, 672 is 1
