Given numbers are 365, 220, 821, 672

The list of prime factors of all numbers are

Prime factors of 365 are 5 x 73

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 821 are 821

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 365, 220, 821, 672

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

Apply this formula for all numbers.

Step1:

LCM(365, 220) = 16060

GCD(365, 220) = ( 365 x 220 ) / 16060

= 365 / 220

= 365

Step2:

LCM(5, 821) = 4105

GCD(5, 821) = ( 5 x 821 ) / 4105

= 5 / 821

= 5

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 365, 220, 821, 672 is 1
