Given numbers are 403, 146, 673, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 146) = 58838
GCD(403, 146) = ( 403 x 146 ) / 58838
= 403 / 146
= 403
Step2:
LCM(1, 673) = 673
GCD(1, 673) = ( 1 x 673 ) / 673
= 1 / 673
= 1
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 403, 146, 673, 210 is 1
