Given numbers are 630, 234, 579, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 234) = 8190
GCD(630, 234) = ( 630 x 234 ) / 8190
= 630 / 234
= 630
Step2:
LCM(18, 579) = 3474
GCD(18, 579) = ( 18 x 579 ) / 3474
= 18 / 579
= 18
Step3:
LCM(3, 809) = 2427
GCD(3, 809) = ( 3 x 809 ) / 2427
= 3 / 809
= 3
So, Greatest Common Divisor of 630, 234, 579, 809 is 1
