Given numbers are 612, 420, 239
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(612, 420) = 21420
GCD(612, 420) = ( 612 x 420 ) / 21420
= 612 / 420
= 612
Step2:
LCM(12, 239) = 2868
GCD(12, 239) = ( 12 x 239 ) / 2868
= 12 / 239
= 12
So, Greatest Common Divisor of 612, 420, 239 is 1
