GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(238, 430) = 51170
GCD(238, 430) = ( 238 x 430 ) / 51170
= 238 / 430
= 238
Step2:
LCM(2, 939) = 1878
GCD(2, 939) = ( 2 x 939 ) / 1878
= 2 / 939
= 2
Step3:
LCM(1, 208) = 208
GCD(1, 208) = ( 1 x 208 ) / 208
= 1 / 208
= 1
So, Greatest Common Divisor of 238, 430, 939, 208 is 1
