Given numbers are 755, 816, 638, 672

The list of prime factors of all numbers are

Prime factors of 755 are 5 x 151

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 638 are 2 x 11 x 29

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 755, 816, 638, 672

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

Apply this formula for all numbers.

Step1:

LCM(755, 816) = 616080

GCD(755, 816) = ( 755 x 816 ) / 616080

= 755 / 816

= 755

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 755, 816, 638, 672 is 1
