Given numbers are 395, 235, 210, 669
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 235) = 18565
GCD(395, 235) = ( 395 x 235 ) / 18565
= 395 / 235
= 395
Step2:
LCM(5, 210) = 210
GCD(5, 210) = ( 5 x 210 ) / 210
= 5 / 210
= 5
Step3:
LCM(5, 669) = 3345
GCD(5, 669) = ( 5 x 669 ) / 3345
= 5 / 669
= 5
So, Greatest Common Divisor of 395, 235, 210, 669 is 1
