GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(814, 396) = 14652
GCD(814, 396) = ( 814 x 396 ) / 14652
= 814 / 396
= 814
Step2:
LCM(22, 890) = 9790
GCD(22, 890) = ( 22 x 890 ) / 9790
= 22 / 890
= 22
Step3:
LCM(2, 656) = 656
GCD(2, 656) = ( 2 x 656 ) / 656
= 2 / 656
= 2
So, Greatest Common Divisor of 814, 396, 890, 656 is 2
