Given numbers are 393, 765, 161, 240
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 765) = 100215
GCD(393, 765) = ( 393 x 765 ) / 100215
= 393 / 765
= 393
Step2:
LCM(3, 161) = 483
GCD(3, 161) = ( 3 x 161 ) / 483
= 3 / 161
= 3
Step3:
LCM(1, 240) = 240
GCD(1, 240) = ( 1 x 240 ) / 240
= 1 / 240
= 1
So, Greatest Common Divisor of 393, 765, 161, 240 is 1
