GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 660) = 157740
GCD(478, 660) = ( 478 x 660 ) / 157740
= 478 / 660
= 478
Step2:
LCM(2, 458) = 458
GCD(2, 458) = ( 2 x 458 ) / 458
= 2 / 458
= 2
Step3:
LCM(2, 346) = 346
GCD(2, 346) = ( 2 x 346 ) / 346
= 2 / 346
= 2
So, Greatest Common Divisor of 478, 660, 458, 346 is 2
