Given numbers are 120, 966, 821, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 966) = 19320
GCD(120, 966) = ( 120 x 966 ) / 19320
= 120 / 966
= 120
Step2:
LCM(6, 821) = 4926
GCD(6, 821) = ( 6 x 821 ) / 4926
= 6 / 821
= 6
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 120, 966, 821, 423 is 1
