Given numbers are 931, 910, 386, 990
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(931, 910) = 121030
GCD(931, 910) = ( 931 x 910 ) / 121030
= 931 / 910
= 931
Step2:
LCM(7, 386) = 2702
GCD(7, 386) = ( 7 x 386 ) / 2702
= 7 / 386
= 7
Step3:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
So, Greatest Common Divisor of 931, 910, 386, 990 is 1
