GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(144, 252) = 1008
GCD(144, 252) = ( 144 x 252 ) / 1008
= 144 / 252
= 144
Step2:
LCM(36, 434) = 7812
GCD(36, 434) = ( 36 x 434 ) / 7812
= 36 / 434
= 36
Step3:
LCM(2, 390) = 390
GCD(2, 390) = ( 2 x 390 ) / 390
= 2 / 390
= 2
So, Greatest Common Divisor of 144, 252, 434, 390 is 2
