GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 342) = 7182
GCD(189, 342) = ( 189 x 342 ) / 7182
= 189 / 342
= 189
Step2:
LCM(9, 612) = 612
GCD(9, 612) = ( 9 x 612 ) / 612
= 9 / 612
= 9
Step3:
LCM(9, 236) = 2124
GCD(9, 236) = ( 9 x 236 ) / 2124
= 9 / 236
= 9
So, Greatest Common Divisor of 189, 342, 612, 236 is 1
