Find LCM of 552,309,721,552 with Prime Factorization
| 2 | 552, 309, 721, 552 |
| 2 | 276, 309, 721, 276 |
| 2 | 138, 309, 721, 138 |
| 3 | 69, 309, 721, 69 |
| 23 | 23, 103, 721, 23 |
| 103 | 1, 103, 721, 1 |
| 1, 1, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 23 x 103 x 1 x 1 x 7 x 1 = 397992
Therefore, the lowest common multiple of 552,309,721,552 is 397992.
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.
552 x 309 x 721 x 552 = 67884699456
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.
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
309 : 1, 3, 103, 309
721 : 1, 7, 103, 721
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 552,309,721,552, is 1.
Now, the common factors can be found like this.
552:2x 2x 2x 3x 23
309:3x 103
721:7x 103
552:2x 2x 2x 3x 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 2x 2x 3x 3x 23x 103 = 170568
Therefore, the value for common factors is 170568.
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 = 67884699456/(1x170568)
LCM = 67884699456/170568
LCM = 397992
Thus, we can understand that the LCM of 552,309,721,552 is 397992.
