GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(986, 756) = 372708
GCD(986, 756) = ( 986 x 756 ) / 372708
= 986 / 756
= 986
Step2:
LCM(2, 392) = 392
GCD(2, 392) = ( 2 x 392 ) / 392
= 2 / 392
= 2
Step3:
LCM(2, 666) = 666
GCD(2, 666) = ( 2 x 666 ) / 666
= 2 / 666
= 2
So, Greatest Common Divisor of 986, 756, 392, 666 is 2
