GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(346, 408) = 70584
GCD(346, 408) = ( 346 x 408 ) / 70584
= 346 / 408
= 346
Step2:
LCM(2, 648) = 648
GCD(2, 648) = ( 2 x 648 ) / 648
= 2 / 648
= 2
Step3:
LCM(2, 406) = 406
GCD(2, 406) = ( 2 x 406 ) / 406
= 2 / 406
= 2
So, Greatest Common Divisor of 346, 408, 648, 406 is 2
