GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 402) = 51858
GCD(387, 402) = ( 387 x 402 ) / 51858
= 387 / 402
= 387
Step2:
LCM(3, 231) = 231
GCD(3, 231) = ( 3 x 231 ) / 231
= 3 / 231
= 3
Step3:
LCM(3, 786) = 786
GCD(3, 786) = ( 3 x 786 ) / 786
= 3 / 786
= 3
So, Greatest Common Divisor of 387, 402, 231, 786 is 3
