Given numbers are 154,447,749,663,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,447,749,663,874 is 711353925282.
Find LCM of 154,447,749,663,874 with Prime Factorization
| 2 | 154, 447, 749, 663, 874 |
| 3 | 77, 447, 749, 663, 437 |
| 7 | 77, 149, 749, 221, 437 |
| 11, 149, 107, 221, 437 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 149 x 107 x 221 x 437 = 711353925282
Therefore, the lowest common multiple of 154,447,749,663,874 is 711353925282.
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 447 x 749 x 663 x 874 = 29876864861844
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
447 : 1, 3, 149, 447
749 : 1, 7, 107, 749
663 : 1, 3, 13, 17, 39, 51, 221, 663
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,447,749,663,874, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
447:3x 149
749:7x 107
663:3x 13x 17
874:2x 19x 23
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 7 = 42
Therefore, the value for common factors is 42.
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 = 29876864861844/(1x42)
LCM = 29876864861844/42
LCM = 711353925282
Thus, we can understand that the LCM of 154,447,749,663,874 is 711353925282.
