Given numbers are 643, 651, 862, 731

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 651 are 3 x 7 x 31

Prime factors of 862 are 2 x 431

Prime factors of 731 are 17 x 43

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

Given numbers are 643, 651, 862, 731

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

Apply this formula for all numbers.

Step1:

LCM(643, 651) = 418593

GCD(643, 651) = ( 643 x 651 ) / 418593

= 643 / 651

= 643

Step2:

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

= 1 / 862

= 1

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 643, 651, 862, 731 is 1
