Given numbers are 212, 142, 394, 890

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

Apply this formula for all numbers.

Step1:

LCM(212, 142) = 15052

GCD(212, 142) = ( 212 x 142 ) / 15052

= 212 / 142

= 212

Step2:

LCM(2, 394) = 394

GCD(2, 394) = ( 2 x 394 ) / 394

= 2 / 394

= 2

Step3:

LCM(2, 890) = 890

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

= 2 / 890

= 2

So, Greatest Common Divisor of 212, 142, 394, 890 is 2
