Given numbers are 998, 686, 238, 931
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(998, 686) = 342314
GCD(998, 686) = ( 998 x 686 ) / 342314
= 998 / 686
= 998
Step2:
LCM(2, 238) = 238
GCD(2, 238) = ( 2 x 238 ) / 238
= 2 / 238
= 2
Step3:
LCM(2, 931) = 1862
GCD(2, 931) = ( 2 x 931 ) / 1862
= 2 / 931
= 2
So, Greatest Common Divisor of 998, 686, 238, 931 is 1
