Given numbers are 393, 954, 655, 810
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 954) = 124974
GCD(393, 954) = ( 393 x 954 ) / 124974
= 393 / 954
= 393
Step2:
LCM(3, 655) = 1965
GCD(3, 655) = ( 3 x 655 ) / 1965
= 3 / 655
= 3
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 393, 954, 655, 810 is 1
