Find LCM of 916,456,855,840 with Prime Factorization
| 2 | 916, 456, 855, 840 |
| 2 | 458, 228, 855, 420 |
| 2 | 229, 114, 855, 210 |
| 3 | 229, 57, 855, 105 |
| 5 | 229, 19, 285, 35 |
| 19 | 229, 19, 57, 7 |
| 229, 1, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 19 x 229 x 1 x 3 x 7 = 10964520
Therefore, the lowest common multiple of 916,456,855,840 is 10964520.
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.
916 x 456 x 855 x 840 = 299989267200
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.
916 : 1, 2, 4, 229, 458, 916
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,456,855,840, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
456:2x 2x 2x 3x 19
855:3x 3x 5x 19
840:2x 2x 2x 3x 5x 7
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 2x 3x 3x 5x 19 = 27360
Therefore, the value for common factors is 27360.
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 = 299989267200/(1x27360)
LCM = 299989267200/27360
LCM = 10964520
Thus, we can understand that the LCM of 916,456,855,840 is 10964520.
