Given numbers are 640, 410, 860, 111

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 410 are 2 x 5 x 41

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 111 are 3 x 37

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

Given numbers are 640, 410, 860, 111

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

Apply this formula for all numbers.

Step1:

LCM(640, 410) = 26240

GCD(640, 410) = ( 640 x 410 ) / 26240

= 640 / 410

= 640

Step2:

LCM(10, 860) = 860

GCD(10, 860) = ( 10 x 860 ) / 860

= 10 / 860

= 10

Step3:

LCM(10, 111) = 1110

GCD(10, 111) = ( 10 x 111 ) / 1110

= 10 / 111

= 10

So, Greatest Common Divisor of 640, 410, 860, 111 is 1
