|
Answer» 1080Step-by-step explanation:it is SAID smallest 4 digit number, so the number will be from 1000 to 9999.36=2*2*3*3 = 2^2 x 3^2 40=2*2*2*5 = 2^3 x 5 45=3*3*5 = 3^2 x 5here , 3 is common now if we check the LCM( of 36,40,45), we GET 8*9*5= 8*45=360the smallest number is 3, 360*3=1080∴this number also LIES between 1000 and 9999.so we can AGREE for this to be the answer. |
