Given numbers are 429, 482, 840, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(429, 482) = 206778
GCD(429, 482) = ( 429 x 482 ) / 206778
= 429 / 482
= 429
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 429, 482, 840, 155 is 1
