Given numbers are 429, 871, 835, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(429, 871) = 28743
GCD(429, 871) = ( 429 x 871 ) / 28743
= 429 / 871
= 429
Step2:
LCM(13, 835) = 10855
GCD(13, 835) = ( 13 x 835 ) / 10855
= 13 / 835
= 13
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 429, 871, 835, 393 is 1
