Given numbers are 551, 840, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(551, 840) = 462840
GCD(551, 840) = ( 551 x 840 ) / 462840
= 551 / 840
= 551
Step2:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
So, Greatest Common Divisor of 551, 840, 231 is 1
