Given numbers are 720, 387, 695, 672

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 387 are 3 x 3 x 43

Prime factors of 695 are 5 x 139

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 720, 387, 695, 672

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

Apply this formula for all numbers.

Step1:

LCM(720, 387) = 30960

GCD(720, 387) = ( 720 x 387 ) / 30960

= 720 / 387

= 720

Step2:

LCM(9, 695) = 6255

GCD(9, 695) = ( 9 x 695 ) / 6255

= 9 / 695

= 9

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 720, 387, 695, 672 is 1
