Given numbers are 432, 305, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 305) = 131760
GCD(432, 305) = ( 432 x 305 ) / 131760
= 432 / 305
= 432
Step2:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 432, 305, 790 is 1
