LCD(3, 40) = 120
It is: 40
To find the Least Common Denominator (LCD) of fractions, you first need to factor the denominators. The denominators are 40 and 18, which can be factored into 2^3 * 5 and 2 * 3^2, respectively. To find the LCD, you take the highest power of each prime factor that appears in either denominator, which in this case is 2^3 * 3^2 * 5. Therefore, the LCD of 3k/40 and k/18 is 2^3 * 3^2 * 5.
If that's 3/8 and 7/10, the LCD is 40.If not, it's 13490
LCD(32, 40) = 160
LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320
40
1 = 1/1, 40 = 40/1 so LCD(1, 40) = 1.
LCD(5, 18) = 90
LCD(40, 50) = 200
