Given numbers are 495, 966, 178, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(495, 966) = 159390
GCD(495, 966) = ( 495 x 966 ) / 159390
= 495 / 966
= 495
Step2:
LCM(3, 178) = 534
GCD(3, 178) = ( 3 x 178 ) / 534
= 3 / 178
= 3
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 495, 966, 178, 391 is 1
