Given numbers are 890, 870, 721

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

Apply this formula for all numbers.

Step1:

LCM(890, 870) = 77430

GCD(890, 870) = ( 890 x 870 ) / 77430

= 890 / 870

= 890

Step2:

LCM(10, 721) = 7210

GCD(10, 721) = ( 10 x 721 ) / 7210

= 10 / 721

= 10

So, Greatest Common Divisor of 890, 870, 721 is 1
