Given numbers are 458,644,943,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 458,644,943,280 is 60465160.
Find LCM of 458,644,943,280 with Prime Factorization
| 2 | 458, 644, 943, 280 |
| 2 | 229, 322, 943, 140 |
| 7 | 229, 161, 943, 70 |
| 23 | 229, 23, 943, 10 |
| 229, 1, 41, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 23 x 229 x 1 x 41 x 10 = 60465160
Therefore, the lowest common multiple of 458,644,943,280 is 60465160.
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.
458 x 644 x 943 x 280 = 77879126080
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.
458 : 1, 2, 229, 458
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
943 : 1, 23, 41, 943
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 458,644,943,280, is 1.
Now, the common factors can be found like this.
458:2x 229
644:2x 2x 7x 23
943:23x 41
280:2x 2x 2x 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 7x 23 = 1288
Therefore, the value for common factors is 1288.
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 = 77879126080/(1x1288)
LCM = 77879126080/1288
LCM = 60465160
Thus, we can understand that the LCM of 458,644,943,280 is 60465160.
