GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(318, 660) = 34980
GCD(318, 660) = ( 318 x 660 ) / 34980
= 318 / 660
= 318
Step2:
LCM(6, 190) = 570
GCD(6, 190) = ( 6 x 190 ) / 570
= 6 / 190
= 6
Step3:
LCM(2, 978) = 978
GCD(2, 978) = ( 2 x 978 ) / 978
= 2 / 978
= 2
So, Greatest Common Divisor of 318, 660, 190, 978 is 2
