Given numbers are 870, 129, 447, 794

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

Apply this formula for all numbers.

Step1:

LCM(870, 129) = 37410

GCD(870, 129) = ( 870 x 129 ) / 37410

= 870 / 129

= 870

Step2:

LCM(3, 447) = 447

GCD(3, 447) = ( 3 x 447 ) / 447

= 3 / 447

= 3

Step3:

LCM(3, 794) = 2382

GCD(3, 794) = ( 3 x 794 ) / 2382

= 3 / 794

= 3

So, Greatest Common Divisor of 870, 129, 447, 794 is 1
