Given numbers are 642, 571, 456, 766

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 571 are 571

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 766 are 2 x 383

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

Given numbers are 642, 571, 456, 766

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

Apply this formula for all numbers.

Step1:

LCM(642, 571) = 366582

GCD(642, 571) = ( 642 x 571 ) / 366582

= 642 / 571

= 642

Step2:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

Step3:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

So, Greatest Common Divisor of 642, 571, 456, 766 is 1
