Given numbers are 418, 243, 831, 361
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(418, 243) = 101574
GCD(418, 243) = ( 418 x 243 ) / 101574
= 418 / 243
= 418
Step2:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
Step3:
LCM(1, 361) = 361
GCD(1, 361) = ( 1 x 361 ) / 361
= 1 / 361
= 1
So, Greatest Common Divisor of 418, 243, 831, 361 is 1
