Given numbers are 685, 870, 848, 287

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 848 are 2 x 2 x 2 x 2 x 53

Prime factors of 287 are 7 x 41

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

Given numbers are 685, 870, 848, 287

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

Apply this formula for all numbers.

Step1:

LCM(685, 870) = 119190

GCD(685, 870) = ( 685 x 870 ) / 119190

= 685 / 870

= 685

Step2:

LCM(5, 848) = 4240

GCD(5, 848) = ( 5 x 848 ) / 4240

= 5 / 848

= 5

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 685, 870, 848, 287 is 1
