Given numbers are 966, 789, 243, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(966, 789) = 254058
GCD(966, 789) = ( 966 x 789 ) / 254058
= 966 / 789
= 966
Step2:
LCM(3, 243) = 243
GCD(3, 243) = ( 3 x 243 ) / 243
= 3 / 243
= 3
Step3:
LCM(3, 491) = 1473
GCD(3, 491) = ( 3 x 491 ) / 1473
= 3 / 491
= 3
So, Greatest Common Divisor of 966, 789, 243, 491 is 1
