Given numbers are 870, 455, 685, 587

The list of prime factors of all numbers are

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

Prime factors of 455 are 5 x 7 x 13

Prime factors of 685 are 5 x 137

Prime factors of 587 are 587

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

Given numbers are 870, 455, 685, 587

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

Apply this formula for all numbers.

Step1:

LCM(870, 455) = 79170

GCD(870, 455) = ( 870 x 455 ) / 79170

= 870 / 455

= 870

Step2:

LCM(5, 685) = 685

GCD(5, 685) = ( 5 x 685 ) / 685

= 5 / 685

= 5

Step3:

LCM(5, 587) = 2935

GCD(5, 587) = ( 5 x 587 ) / 2935

= 5 / 587

= 5

So, Greatest Common Divisor of 870, 455, 685, 587 is 1
