Given numbers are 631,260,358,860,458
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,260,358,860,458 is 289174288780.
Find LCM of 631,260,358,860,458 with Prime Factorization
| 2 | 631, 260, 358, 860, 458 |
| 2 | 631, 130, 179, 430, 229 |
| 5 | 631, 65, 179, 215, 229 |
| 631, 13, 179, 43, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 631 x 13 x 179 x 43 x 229 = 289174288780
Therefore, the lowest common multiple of 631,260,358,860,458 is 289174288780.
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.
631 x 260 x 358 x 860 x 458 = 23133943102400
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.
631 : 1, 631
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
358 : 1, 2, 179, 358
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
458 : 1, 2, 229, 458
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,260,358,860,458, is 1.
Now, the common factors can be found like this.
631:631
260:2x 2x 5x 13
358:2x 179
860:2x 2x 5x 43
458:2x 229
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 5 = 80
Therefore, the value for common factors is 80.
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 = 23133943102400/(1x80)
LCM = 23133943102400/80
LCM = 289174288780
Thus, we can understand that the LCM of 631,260,358,860,458 is 289174288780.
