GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 385) = 162855
GCD(423, 385) = ( 423 x 385 ) / 162855
= 423 / 385
= 423
Step2:
LCM(1, 440) = 440
GCD(1, 440) = ( 1 x 440 ) / 440
= 1 / 440
= 1
Step3:
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
= 1 / 798
= 1
So, Greatest Common Divisor of 423, 385, 440, 798 is 1
