Given numbers are 746, 800, 642, 861

The list of prime factors of all numbers are

Prime factors of 746 are 2 x 373

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 642 are 2 x 3 x 107

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 746, 800, 642, 861

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

Apply this formula for all numbers.

Step1:

LCM(746, 800) = 298400

GCD(746, 800) = ( 746 x 800 ) / 298400

= 746 / 800

= 746

Step2:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

Step3:

LCM(2, 861) = 1722

GCD(2, 861) = ( 2 x 861 ) / 1722

= 2 / 861

= 2

So, Greatest Common Divisor of 746, 800, 642, 861 is 1
