Given numbers are 300, 642, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(300, 642) = 32100
GCD(300, 642) = ( 300 x 642 ) / 32100
= 300 / 642
= 300
Step2:
LCM(6, 123) = 246
GCD(6, 123) = ( 6 x 123 ) / 246
= 6 / 123
= 6
So, Greatest Common Divisor of 300, 642, 123 is 3
