Given numbers are 234, 165, 989, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(234, 165) = 12870
GCD(234, 165) = ( 234 x 165 ) / 12870
= 234 / 165
= 234
Step2:
LCM(3, 989) = 2967
GCD(3, 989) = ( 3 x 989 ) / 2967
= 3 / 989
= 3
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 234, 165, 989, 393 is 1
