Given numbers are 721, 842, 57

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

Apply this formula for all numbers.

Step1:

LCM(721, 842) = 607082

GCD(721, 842) = ( 721 x 842 ) / 607082

= 721 / 842

= 721

Step2:

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

= 1 / 57

= 1

So, Greatest Common Divisor of 721, 842, 57 is 1
