Given numbers are 506, 638, 44, 870

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

Apply this formula for all numbers.

Step1:

LCM(506, 638) = 14674

GCD(506, 638) = ( 506 x 638 ) / 14674

= 506 / 638

= 506

Step2:

LCM(22, 44) = 44

GCD(22, 44) = ( 22 x 44 ) / 44

= 22 / 44

= 22

Step3:

LCM(22, 870) = 9570

GCD(22, 870) = ( 22 x 870 ) / 9570

= 22 / 870

= 22

So, Greatest Common Divisor of 506, 638, 44, 870 is 2
