Find LCM of 912,131,240,817 with Prime Factorization
| 2 | 912, 131, 240, 817 |
| 2 | 456, 131, 120, 817 |
| 2 | 228, 131, 60, 817 |
| 2 | 114, 131, 30, 817 |
| 3 | 57, 131, 15, 817 |
| 19 | 19, 131, 5, 817 |
| 1, 131, 5, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 19 x 1 x 131 x 5 x 43 = 25686480
Therefore, the lowest common multiple of 912,131,240,817 is 25686480.
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.
912 x 131 x 240 x 817 = 23426069760
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
131 : 1, 131
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,131,240,817, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
131:131
240:2x 2x 2x 2x 3x 5
817:19x 43
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 2x 3x 19 = 912
Therefore, the value for common factors is 912.
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 = 23426069760/(1x912)
LCM = 23426069760/912
LCM = 25686480
Thus, we can understand that the LCM of 912,131,240,817 is 25686480.
