Given numbers are 966, 980, 991, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(966, 980) = 67620
GCD(966, 980) = ( 966 x 980 ) / 67620
= 966 / 980
= 966
Step2:
LCM(14, 991) = 13874
GCD(14, 991) = ( 14 x 991 ) / 13874
= 14 / 991
= 14
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 966, 980, 991, 154 is 1
