Given numbers are 678, 966, 678, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 966) = 109158
GCD(678, 966) = ( 678 x 966 ) / 109158
= 678 / 966
= 678
Step2:
LCM(6, 678) = 678
GCD(6, 678) = ( 6 x 678 ) / 678
= 6 / 678
= 6
Step3:
LCM(6, 421) = 2526
GCD(6, 421) = ( 6 x 421 ) / 2526
= 6 / 421
= 6
So, Greatest Common Divisor of 678, 966, 678, 421 is 1
