Given numbers are 642, 288, 799, 427

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 799 are 17 x 47

Prime factors of 427 are 7 x 61

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

Given numbers are 642, 288, 799, 427

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

Apply this formula for all numbers.

Step1:

LCM(642, 288) = 30816

GCD(642, 288) = ( 642 x 288 ) / 30816

= 642 / 288

= 642

Step2:

LCM(6, 799) = 4794

GCD(6, 799) = ( 6 x 799 ) / 4794

= 6 / 799

= 6

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 642, 288, 799, 427 is 1
