Given numbers are 721, 568, 213

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

Apply this formula for all numbers.

Step1:

LCM(721, 568) = 409528

GCD(721, 568) = ( 721 x 568 ) / 409528

= 721 / 568

= 721

Step2:

LCM(1, 213) = 213

GCD(1, 213) = ( 1 x 213 ) / 213

= 1 / 213

= 1

So, Greatest Common Divisor of 721, 568, 213 is 1
