Find LCM of 456,855,117,624 with Prime Factorization
| 2 | 456, 855, 117, 624 |
| 2 | 228, 855, 117, 312 |
| 2 | 114, 855, 117, 156 |
| 3 | 57, 855, 117, 78 |
| 3 | 19, 285, 39, 26 |
| 13 | 19, 95, 13, 26 |
| 19 | 19, 95, 1, 2 |
| 1, 5, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 13 x 19 x 1 x 5 x 1 x 2 = 177840
Therefore, the lowest common multiple of 456,855,117,624 is 177840.
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.
456 x 855 x 117 x 624 = 28464359040
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.
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
117 : 1, 3, 9, 13, 39, 117
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,855,117,624, is 3.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
855:3x 3x 5x 19
117:3x 3x 13
624:2x 2x 2x 2x 3x 13
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 3x 3x 3x 13x 19 = 53352
Therefore, the value for common factors is 53352.
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 = 28464359040/(3x53352)
LCM = 28464359040/160056
LCM = 177840
Thus, we can understand that the LCM of 456,855,117,624 is 177840.
