Given numbers are 402, 429, 103, 855
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 429) = 57486
GCD(402, 429) = ( 402 x 429 ) / 57486
= 402 / 429
= 402
Step2:
LCM(3, 103) = 309
GCD(3, 103) = ( 3 x 103 ) / 309
= 3 / 103
= 3
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 402, 429, 103, 855 is 1
