Find LCM of 913,646,456,440 with Prime Factorization
| 2 | 913, 646, 456, 440 |
| 2 | 913, 323, 228, 220 |
| 2 | 913, 323, 114, 110 |
| 11 | 913, 323, 57, 55 |
| 19 | 83, 323, 57, 5 |
| 83, 17, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 19 x 83 x 17 x 3 x 5 = 35387880
Therefore, the lowest common multiple of 913,646,456,440 is 35387880.
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.
913 x 646 x 456 x 440 = 118337070720
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.
913 : 1, 11, 83, 913
646 : 1, 2, 17, 19, 34, 38, 323, 646
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,646,456,440, is 1.
Now, the common factors can be found like this.
913:11x 83
646:2x 17x 19
456:2x 2x 2x 3x 19
440:2x 2x 2x 5x 11
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 11x 19 = 3344
Therefore, the value for common factors is 3344.
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 = 118337070720/(1x3344)
LCM = 118337070720/3344
LCM = 35387880
Thus, we can understand that the LCM of 913,646,456,440 is 35387880.
