the answer is 14
385 5*77 = 385 7*77 = 385 11*35 = 385
18 is.
45
It is: 176
75
LCM(8, 9, 27) = 216
Yes.
40 and 72
1 x 7 = 71 x 5 = 52 x 7 = 142 x 5 = 103 x 7 = 213 x 5 = 154 x 7 = 284 x 5 = 205 x 7 = 355 x 5 = 256 x 5 = 307 x 5 = 35It is the first and lowest multiple that 5 and 7 have in common, therefore, it is called the least common multiple.
2/7 * 14 = 2/7 * (7*2) = 2/7 * 7 * 2 cancelling out the 7s = 2 * 2 = 4
31/2 / 21/3 = (7/2) / (7/3) = (7/2)*(3/7) = 3/2 or 11/231/2 / 21/3 = (7/2) / (7/3) = (7/2)*(3/7) = 3/2 or 11/231/2 / 21/3 = (7/2) / (7/3) = (7/2)*(3/7) = 3/2 or 11/231/2 / 21/3 = (7/2) / (7/3) = (7/2)*(3/7) = 3/2 or 11/2
Let's see in a prime factorization tree. 2, 98 2, 2, 49 2, 2, 7, 7. The answer is:2 to the power of 2 and 7 to the power of 2 ;/or 2 x 2 x 7 x 7
