Given numbers are 345, 138, 86, 429
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 138) = 690
GCD(345, 138) = ( 345 x 138 ) / 690
= 345 / 138
= 345
Step2:
LCM(69, 86) = 5934
GCD(69, 86) = ( 69 x 86 ) / 5934
= 69 / 86
= 69
Step3:
LCM(1, 429) = 429
GCD(1, 429) = ( 1 x 429 ) / 429
= 1 / 429
= 1
So, Greatest Common Divisor of 345, 138, 86, 429 is 1
