Given numbers are 143,990,143,635
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,990,143,635 is 1634490.
Find LCM of 143,990,143,635 with Prime Factorization
| 5 | 143, 990, 143, 635 |
| 11 | 143, 198, 143, 127 |
| 13 | 13, 18, 13, 127 |
| 1, 18, 1, 127 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 1 x 18 x 1 x 127 = 1634490
Therefore, the lowest common multiple of 143,990,143,635 is 1634490.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
143 x 990 x 143 x 635 = 12855263850
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
143 : 1, 11, 13, 143
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
143 : 1, 11, 13, 143
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,990,143,635, is 1.
Now, the common factors can be found like this.
143:11x 13
990:2x 3x 3x 5x 11
143:11x 13
635:5x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11x 13 = 7865
Therefore, the value for common factors is 7865.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 12855263850/(1x7865)
LCM = 12855263850/7865
LCM = 1634490
Thus, we can understand that the LCM of 143,990,143,635 is 1634490.
