Given numbers are 314,312,304,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 314,312,304,840 is 65148720.
Find LCM of 314,312,304,840 with Prime Factorization
| 2 | 314, 312, 304, 840 |
| 2 | 157, 156, 152, 420 |
| 2 | 157, 78, 76, 210 |
| 3 | 157, 39, 38, 105 |
| 157, 13, 38, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 157 x 13 x 38 x 35 = 65148720
Therefore, the lowest common multiple of 314,312,304,840 is 65148720.
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.
314 x 312 x 304 x 840 = 25017108480
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.
314 : 1, 2, 157, 314
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 314,312,304,840, is 2.
Now, the common factors can be found like this.
314:2x 157
312:2x 2x 2x 3x 13
304:2x 2x 2x 2x 19
840:2x 2x 2x 3x 5x 7
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 = 25017108480/(2x192)
LCM = 25017108480/384
LCM = 65148720
Thus, we can understand that the LCM of 314,312,304,840 is 65148720.
