Given numbers are 642, 407, 783, 600

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 407 are 11 x 37

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

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

Given numbers are 642, 407, 783, 600

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

Apply this formula for all numbers.

Step1:

LCM(642, 407) = 261294

GCD(642, 407) = ( 642 x 407 ) / 261294

= 642 / 407

= 642

Step2:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

Step3:

LCM(1, 600) = 600

GCD(1, 600) = ( 1 x 600 ) / 600

= 1 / 600

= 1

So, Greatest Common Divisor of 642, 407, 783, 600 is 1
