Given numbers are 720, 361, 64
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 361) = 259920
GCD(720, 361) = ( 720 x 361 ) / 259920
= 720 / 361
= 720
Step2:
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
= 1 / 64
= 1
So, Greatest Common Divisor of 720, 361, 64 is 1
