Given numbers are 731, 405, 64
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(731, 405) = 296055
GCD(731, 405) = ( 731 x 405 ) / 296055
= 731 / 405
= 731
Step2:
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
= 1 / 64
= 1
So, Greatest Common Divisor of 731, 405, 64 is 1
