Given numbers are 969,225,478,240,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,225,478,240,642 is 29736284400.
Find LCM of 969,225,478,240,642 with Prime Factorization
| 2 | 969, 225, 478, 240, 642 |
| 3 | 969, 225, 239, 120, 321 |
| 5 | 323, 75, 239, 40, 107 |
| 323, 15, 239, 8, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 323 x 15 x 239 x 8 x 107 = 29736284400
Therefore, the lowest common multiple of 969,225,478,240,642 is 29736284400.
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.
969 x 225 x 478 x 240 x 642 = 16057593576000
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
478 : 1, 2, 239, 478
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,225,478,240,642, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
225:3x 3x 5x 5
478:2x 239
240:2x 2x 2x 2x 3x 5
642:2x 3x 107
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 16057593576000/(1x540)
LCM = 16057593576000/540
LCM = 29736284400
Thus, we can understand that the LCM of 969,225,478,240,642 is 29736284400.
