Given numbers are 630, 395, 905, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 395) = 49770
GCD(630, 395) = ( 630 x 395 ) / 49770
= 630 / 395
= 630
Step2:
LCM(5, 905) = 905
GCD(5, 905) = ( 5 x 905 ) / 905
= 5 / 905
= 5
Step3:
LCM(5, 409) = 2045
GCD(5, 409) = ( 5 x 409 ) / 2045
= 5 / 409
= 5
So, Greatest Common Divisor of 630, 395, 905, 409 is 1
