Given numbers are 870, 853, 658

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

Apply this formula for all numbers.

Step1:

LCM(870, 853) = 742110

GCD(870, 853) = ( 870 x 853 ) / 742110

= 870 / 853

= 870

Step2:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 870, 853, 658 is 1
