Given numbers are 143,689,742,166
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,689,742,166 is 8806798.
Find LCM of 143,689,742,166 with Prime Factorization
| 2 | 143, 689, 742, 166 |
| 13 | 143, 689, 371, 83 |
| 53 | 11, 53, 371, 83 |
| 11, 1, 7, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 53 x 11 x 1 x 7 x 83 = 8806798
Therefore, the lowest common multiple of 143,689,742,166 is 8806798.
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 689 x 742 x 166 = 12135767644
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
689 : 1, 13, 53, 689
742 : 1, 2, 7, 14, 53, 106, 371, 742
166 : 1, 2, 83, 166
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,689,742,166, is 1.
Now, the common factors can be found like this.
143:11x 13
689:13x 53
742:2x 7x 53
166:2x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 53 = 1378
Therefore, the value for common factors is 1378.
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 = 12135767644/(1x1378)
LCM = 12135767644/1378
LCM = 8806798
Thus, we can understand that the LCM of 143,689,742,166 is 8806798.
