GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 213) = 27903
GCD(393, 213) = ( 393 x 213 ) / 27903
= 393 / 213
= 393
Step2:
LCM(3, 688) = 2064
GCD(3, 688) = ( 3 x 688 ) / 2064
= 3 / 688
= 3
Step3:
LCM(1, 135) = 135
GCD(1, 135) = ( 1 x 135 ) / 135
= 1 / 135
= 1
So, Greatest Common Divisor of 393, 213, 688, 135 is 1
