Find LCM of 544,897,390,345 with Prime Factorization
| 2 | 544, 897, 390, 345 |
| 3 | 272, 897, 195, 345 |
| 5 | 272, 299, 65, 115 |
| 13 | 272, 299, 13, 23 |
| 23 | 272, 23, 1, 23 |
| 272, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 23 x 272 x 1 x 1 x 1 = 2439840
Therefore, the lowest common multiple of 544,897,390,345 is 2439840.
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.
544 x 897 x 390 x 345 = 65656094400
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.
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
897 : 1, 3, 13, 23, 39, 69, 299, 897
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 544,897,390,345, is 1.
Now, the common factors can be found like this.
544:2x 2x 2x 2x 2x 17
897:3x 13x 23
390:2x 3x 5x 13
345:3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 13x 23 = 26910
Therefore, the value for common factors is 26910.
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 = 65656094400/(1x26910)
LCM = 65656094400/26910
LCM = 2439840
Thus, we can understand that the LCM of 544,897,390,345 is 2439840.
