Given numbers are 685, 858, 770, 907

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 907 are 907

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

Given numbers are 685, 858, 770, 907

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

Apply this formula for all numbers.

Step1:

LCM(685, 858) = 587730

GCD(685, 858) = ( 685 x 858 ) / 587730

= 685 / 858

= 685

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

= 1 / 907

= 1

So, Greatest Common Divisor of 685, 858, 770, 907 is 1
