Find LCM of 912,928,456,638 with Prime Factorization
2 | 912, 928, 456, 638 |
2 | 456, 464, 228, 319 |
2 | 114, 232, 228, 319 |
2 | 57, 116, 114, 319 |
3 | 57, 58, 57, 319 |
19 | 19, 58, 19, 319 |
29 | 1, 58, 1, 319 |
1, 2, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 19 x 29 x 1 x 2 x 1 x 11 = 581856
Therefore, the lowest common multiple of 912,928,456,638 is 581856.
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 928 x 456 x 638 = 246222839808
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
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
638 : 1, 2, 11, 22, 29, 58, 319, 638
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,928,456,638, is 2.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
928:2x 2x 2x 2x 2x 29
456:2x 2x 2x 3x 19
638:2x 11x 29
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 2x 2x 3x 19x 29 = 211584
Therefore, the value for common factors is 211584.
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 = 246222839808/(2x211584)
LCM = 246222839808/423168
LCM = 581856
Thus, we can understand that the LCM of 912,928,456,638 is 581856.
