Given numbers are 258,139,490,478,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 258,139,490,478,288 is 100795171680.
Find LCM of 258,139,490,478,288 with Prime Factorization
| 2 | 258, 139, 490, 478, 288 |
| 3 | 129, 139, 245, 239, 144 |
| 43, 139, 245, 239, 48 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 139 x 245 x 239 x 48 = 100795171680
Therefore, the lowest common multiple of 258,139,490,478,288 is 100795171680.
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.
258 x 139 x 490 x 478 x 288 = 2419084120320
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
139 : 1, 139
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
478 : 1, 2, 239, 478
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,139,490,478,288, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
139:139
490:2x 5x 7x 7
478:2x 239
288:2x 2x 2x 2x 2x 3x 3
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 3 = 24
Therefore, the value for common factors is 24.
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 = 2419084120320/(1x24)
LCM = 2419084120320/24
LCM = 100795171680
Thus, we can understand that the LCM of 258,139,490,478,288 is 100795171680.
