Find LCM of 715,648,309,288 with Prime Factorization
| 2 | 715, 648, 309, 288 |
| 2 | 715, 324, 309, 144 |
| 2 | 715, 162, 309, 72 |
| 3 | 715, 81, 309, 36 |
| 3 | 715, 27, 103, 12 |
| 715, 9, 103, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 715 x 9 x 103 x 4 = 190887840
Therefore, the lowest common multiple of 715,648,309,288 is 190887840.
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.
715 x 648 x 309 x 288 = 41231773440
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
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
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,648,309,288, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
648:2x 2x 2x 3x 3x 3x 3
309:3x 103
288:2x 2x 2x 2x 2x 3x 3
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 3 = 216
Therefore, the value for common factors is 216.
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 = 41231773440/(1x216)
LCM = 41231773440/216
LCM = 190887840
Thus, we can understand that the LCM of 715,648,309,288 is 190887840.
