Given numbers are 890, 420, 139

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

Apply this formula for all numbers.

Step1:

LCM(890, 420) = 37380

GCD(890, 420) = ( 890 x 420 ) / 37380

= 890 / 420

= 890

Step2:

LCM(10, 139) = 1390

GCD(10, 139) = ( 10 x 139 ) / 1390

= 10 / 139

= 10

So, Greatest Common Divisor of 890, 420, 139 is 1
