Given numbers are 685, 100, 777, 860

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 777 are 3 x 7 x 37

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

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

Given numbers are 685, 100, 777, 860

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

Apply this formula for all numbers.

Step1:

LCM(685, 100) = 13700

GCD(685, 100) = ( 685 x 100 ) / 13700

= 685 / 100

= 685

Step2:

LCM(5, 777) = 3885

GCD(5, 777) = ( 5 x 777 ) / 3885

= 5 / 777

= 5

Step3:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 685, 100, 777, 860 is 1
