Given numbers are 630, 306, 208, 179
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 306) = 10710
GCD(630, 306) = ( 630 x 306 ) / 10710
= 630 / 306
= 630
Step2:
LCM(18, 208) = 1872
GCD(18, 208) = ( 18 x 208 ) / 1872
= 18 / 208
= 18
Step3:
LCM(2, 179) = 358
GCD(2, 179) = ( 2 x 179 ) / 358
= 2 / 179
= 2
So, Greatest Common Divisor of 630, 306, 208, 179 is 1
