GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 978) = 326652
GCD(668, 978) = ( 668 x 978 ) / 326652
= 668 / 978
= 668
Step2:
LCM(2, 578) = 578
GCD(2, 578) = ( 2 x 578 ) / 578
= 2 / 578
= 2
Step3:
LCM(2, 495) = 990
GCD(2, 495) = ( 2 x 495 ) / 990
= 2 / 495
= 2
So, Greatest Common Divisor of 668, 978, 578, 495 is 1
