GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(662, 330) = 109230
GCD(662, 330) = ( 662 x 330 ) / 109230
= 662 / 330
= 662
Step2:
LCM(2, 556) = 556
GCD(2, 556) = ( 2 x 556 ) / 556
= 2 / 556
= 2
Step3:
LCM(2, 578) = 578
GCD(2, 578) = ( 2 x 578 ) / 578
= 2 / 578
= 2
So, Greatest Common Divisor of 662, 330, 556, 578 is 2
