Given numbers are 721,648,309,824,348
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,648,309,824,348 is 13549032.
Find LCM of 721,648,309,824,348 with Prime Factorization
| 2 | 721, 648, 309, 824, 348 |
| 2 | 721, 324, 309, 412, 174 |
| 2 | 721, 162, 309, 206, 87 |
| 3 | 721, 81, 309, 103, 87 |
| 103 | 721, 27, 103, 103, 29 |
| 7, 27, 1, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 103 x 7 x 27 x 1 x 1 x 29 = 13549032
Therefore, the lowest common multiple of 721,648,309,824,348 is 13549032.
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.
721 x 648 x 309 x 824 x 348 = 41397603980544
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.
721 : 1, 7, 103, 721
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
309 : 1, 3, 103, 309
824 : 1, 2, 4, 8, 103, 206, 412, 824
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,648,309,824,348, is 1.
Now, the common factors can be found like this.
721:7x 103
648:2x 2x 2x 3x 3x 3x 3
309:3x 103
824:2x 2x 2x 103
348:2x 2x 3x 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 3x 3x 103x 103 = 3055392
Therefore, the value for common factors is 3055392.
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 = 41397603980544/(1x3055392)
LCM = 41397603980544/3055392
LCM = 13549032
Thus, we can understand that the LCM of 721,648,309,824,348 is 13549032.
