Given numbers are 287, 638, 210, 919
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 638) = 183106
GCD(287, 638) = ( 287 x 638 ) / 183106
= 287 / 638
= 287
Step2:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
Step3:
LCM(1, 919) = 919
GCD(1, 919) = ( 1 x 919 ) / 919
= 1 / 919
= 1
So, Greatest Common Divisor of 287, 638, 210, 919 is 1
