Given numbers are 668, 315, 905, 810
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 315) = 210420
GCD(668, 315) = ( 668 x 315 ) / 210420
= 668 / 315
= 668
Step2:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 668, 315, 905, 810 is 1
