Given numbers are 747, 403, 72

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

Apply this formula for all numbers.

Step1:

LCM(747, 403) = 301041

GCD(747, 403) = ( 747 x 403 ) / 301041

= 747 / 403

= 747

Step2:

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

= 1 / 72

= 1

So, Greatest Common Divisor of 747, 403, 72 is 1
