Given numbers are 468,745,286,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 468,745,286,220 is 3835260.
Find LCM of 468,745,286,220 with Prime Factorization
| 2 | 468, 745, 286, 220 |
| 2 | 234, 745, 143, 110 |
| 5 | 117, 745, 143, 55 |
| 11 | 117, 149, 143, 11 |
| 13 | 117, 149, 13, 1 |
| 9, 149, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 13 x 9 x 149 x 1 x 1 = 3835260
Therefore, the lowest common multiple of 468,745,286,220 is 3835260.
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.
468 x 745 x 286 x 220 = 21937687200
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.
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
745 : 1, 5, 149, 745
286 : 1, 2, 11, 13, 22, 26, 143, 286
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,745,286,220, is 1.
Now, the common factors can be found like this.
468:2x 2x 3x 3x 13
745:5x 149
286:2x 11x 13
220:2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 11x 13 = 5720
Therefore, the value for common factors is 5720.
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 = 21937687200/(1x5720)
LCM = 21937687200/5720
LCM = 3835260
Thus, we can understand that the LCM of 468,745,286,220 is 3835260.
