Given numbers are 870, 676, 445

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

Apply this formula for all numbers.

Step1:

LCM(870, 676) = 294060

GCD(870, 676) = ( 870 x 676 ) / 294060

= 870 / 676

= 870

Step2:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

So, Greatest Common Divisor of 870, 676, 445 is 1
