GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 604) = 117780
GCD(390, 604) = ( 390 x 604 ) / 117780
= 390 / 604
= 390
Step2:
LCM(2, 468) = 468
GCD(2, 468) = ( 2 x 468 ) / 468
= 2 / 468
= 2
Step3:
LCM(2, 470) = 470
GCD(2, 470) = ( 2 x 470 ) / 470
= 2 / 470
= 2
So, Greatest Common Divisor of 390, 604, 468, 470 is 2
