Given numbers are 642, 811, 153, 672

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 811 are 811

Prime factors of 153 are 3 x 3 x 17

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 642, 811, 153, 672

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

Apply this formula for all numbers.

Step1:

LCM(642, 811) = 520662

GCD(642, 811) = ( 642 x 811 ) / 520662

= 642 / 811

= 642

Step2:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

Step3:

LCM(1, 672) = 672

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

= 1 / 672

= 1

So, Greatest Common Divisor of 642, 811, 153, 672 is 1
