Given numbers are 285, 196, 186, 870

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 196 are 2 x 2 x 7 x 7

Prime factors of 186 are 2 x 3 x 31

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

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

Given numbers are 285, 196, 186, 870

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

Apply this formula for all numbers.

Step1:

LCM(285, 196) = 55860

GCD(285, 196) = ( 285 x 196 ) / 55860

= 285 / 196

= 285

Step2:

LCM(1, 186) = 186

GCD(1, 186) = ( 1 x 186 ) / 186

= 1 / 186

= 1

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 285, 196, 186, 870 is 1
