LCD(21, 13, 14, 15) = 2730
The least common denominator (LCD) is 1.
LCD(13, 16) = 208
It is: 105
It is: 462
20
LCD(49, 21) = 147
the LCD is the LCM (least common multiple) of the two number which is 105 in this case
No, they are integers. If they were denominators, their LCD would be 42.
It is: 294 which is the same as its LCM
13/15 = 65/75 21/25 = 63/75 13/15 is bigger.
13/14 ÷ 21/2 = 13/147
15+6 is 21. 13 + what is 21? 21 - 13 is 8 Eight
