Given numbers are 240,632,307,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 240,632,307,840 is 40745040.
Find LCM of 240,632,307,840 with Prime Factorization
| 2 | 240, 632, 307, 840 |
| 2 | 120, 316, 307, 420 |
| 2 | 60, 158, 307, 210 |
| 3 | 30, 79, 307, 105 |
| 5 | 10, 79, 307, 35 |
| 2, 79, 307, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 2 x 79 x 307 x 7 = 40745040
Therefore, the lowest common multiple of 240,632,307,840 is 40745040.
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.
240 x 632 x 307 x 840 = 39115238400
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
632 : 1, 2, 4, 8, 79, 158, 316, 632
307 : 1, 307
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,632,307,840, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
632:2x 2x 2x 79
307:307
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 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 39115238400/(1x960)
LCM = 39115238400/960
LCM = 40745040
Thus, we can understand that the LCM of 240,632,307,840 is 40745040.
