Given numbers are 720,384,314,484
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,384,314,484 is 109422720.
Find LCM of 720,384,314,484 with Prime Factorization
| 2 | 720, 384, 314, 484 |
| 2 | 360, 192, 157, 242 |
| 2 | 180, 96, 157, 121 |
| 2 | 90, 48, 157, 121 |
| 3 | 45, 24, 157, 121 |
| 15, 8, 157, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 15 x 8 x 157 x 121 = 109422720
Therefore, the lowest common multiple of 720,384,314,484 is 109422720.
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.
720 x 384 x 314 x 484 = 42018324480
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
314 : 1, 2, 157, 314
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,384,314,484, is 2.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
384:2x 2x 2x 2x 2x 2x 2x 3
314:2x 157
484:2x 2x 11x 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 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 42018324480/(2x192)
LCM = 42018324480/384
LCM = 109422720
Thus, we can understand that the LCM of 720,384,314,484 is 109422720.
