Given numbers are 931, 743, 21

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

Apply this formula for all numbers.

Step1:

LCM(931, 743) = 691733

GCD(931, 743) = ( 931 x 743 ) / 691733

= 931 / 743

= 931

Step2:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

So, Greatest Common Divisor of 931, 743, 21 is 1
