Given numbers are 190, 870, 294, 420

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

Apply this formula for all numbers.

Step1:

LCM(190, 870) = 16530

GCD(190, 870) = ( 190 x 870 ) / 16530

= 190 / 870

= 190

Step2:

LCM(10, 294) = 1470

GCD(10, 294) = ( 10 x 294 ) / 1470

= 10 / 294

= 10

Step3:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

So, Greatest Common Divisor of 190, 870, 294, 420 is 2
