Given numbers are 862, 431, 648, 644

The list of prime factors of all numbers are

Prime factors of 862 are 2 x 431

Prime factors of 431 are 431

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 862, 431, 648, 644

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

Apply this formula for all numbers.

Step1:

LCM(862, 431) = 862

GCD(862, 431) = ( 862 x 431 ) / 862

= 862 / 431

= 862

Step2:

LCM(431, 648) = 279288

GCD(431, 648) = ( 431 x 648 ) / 279288

= 431 / 648

= 431

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 862, 431, 648, 644 is 1
