Given numbers are 870, 658, 770, 246

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

Apply this formula for all numbers.

Step1:

LCM(870, 658) = 286230

GCD(870, 658) = ( 870 x 658 ) / 286230

= 870 / 658

= 870

Step2:

LCM(2, 770) = 770

GCD(2, 770) = ( 2 x 770 ) / 770

= 2 / 770

= 2

Step3:

LCM(2, 246) = 246

GCD(2, 246) = ( 2 x 246 ) / 246

= 2 / 246

= 2

So, Greatest Common Divisor of 870, 658, 770, 246 is 2
