Given numbers are 981, 342, 199, 812
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 342) = 37278
GCD(981, 342) = ( 981 x 342 ) / 37278
= 981 / 342
= 981
Step2:
LCM(9, 199) = 1791
GCD(9, 199) = ( 9 x 199 ) / 1791
= 9 / 199
= 9
Step3:
LCM(1, 812) = 812
GCD(1, 812) = ( 1 x 812 ) / 812
= 1 / 812
= 1
So, Greatest Common Divisor of 981, 342, 199, 812 is 1
