Given numbers are 800, 785, 879, 644

The list of prime factors of all numbers are

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

Prime factors of 785 are 5 x 157

Prime factors of 879 are 3 x 293

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 800, 785, 879, 644

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

Apply this formula for all numbers.

Step1:

LCM(800, 785) = 125600

GCD(800, 785) = ( 800 x 785 ) / 125600

= 800 / 785

= 800

Step2:

LCM(5, 879) = 4395

GCD(5, 879) = ( 5 x 879 ) / 4395

= 5 / 879

= 5

Step3:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 800, 785, 879, 644 is 1
