Given numbers are 815, 288, 423, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 288) = 234720
GCD(815, 288) = ( 815 x 288 ) / 234720
= 815 / 288
= 815
Step2:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 815, 288, 423, 394 is 1
