Given numbers are 105, 867, 767, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 867) = 30345
GCD(105, 867) = ( 105 x 867 ) / 30345
= 105 / 867
= 105
Step2:
LCM(3, 767) = 2301
GCD(3, 767) = ( 3 x 767 ) / 2301
= 3 / 767
= 3
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 105, 867, 767, 989 is 1
