Find LCM of 154,819,225,876,949 with Prime Factorization
| 2 | 154, 819, 225, 876, 949 |
| 3 | 77, 819, 225, 438, 949 |
| 3 | 77, 273, 75, 146, 949 |
| 7 | 77, 91, 25, 146, 949 |
| 13 | 11, 13, 25, 146, 949 |
| 73 | 11, 1, 25, 146, 73 |
| 11, 1, 25, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 13 x 73 x 11 x 1 x 25 x 2 x 1 = 65765700
Therefore, the lowest common multiple of 154,819,225,876,949 is 65765700.
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.
154 x 819 x 225 x 876 x 949 = 23591603435400
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,819,225,876,949, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
819:3x 3x 7x 13
225:3x 3x 5x 5
876:2x 2x 3x 73
949:13x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7x 13x 73 = 358722
Therefore, the value for common factors is 358722.
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 = 23591603435400/(1x358722)
LCM = 23591603435400/358722
LCM = 65765700
Thus, we can understand that the LCM of 154,819,225,876,949 is 65765700.
