Given numbers are 572, 838, 645, 816

The list of prime factors of all numbers are

Prime factors of 572 are 2 x 2 x 11 x 13

Prime factors of 838 are 2 x 419

Prime factors of 645 are 3 x 5 x 43

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

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

Given numbers are 572, 838, 645, 816

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

Apply this formula for all numbers.

Step1:

LCM(572, 838) = 239668

GCD(572, 838) = ( 572 x 838 ) / 239668

= 572 / 838

= 572

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 572, 838, 645, 816 is 1
