Given numbers are 231, 636, 843, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 636) = 48972
GCD(231, 636) = ( 231 x 636 ) / 48972
= 231 / 636
= 231
Step2:
LCM(3, 843) = 843
GCD(3, 843) = ( 3 x 843 ) / 843
= 3 / 843
= 3
Step3:
LCM(3, 815) = 2445
GCD(3, 815) = ( 3 x 815 ) / 2445
= 3 / 815
= 3
So, Greatest Common Divisor of 231, 636, 843, 815 is 1
