Given numbers are 515,458,648,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,458,648,521 is 39815799480.
Find LCM of 515,458,648,521 with Prime Factorization
| 2 | 515, 458, 648, 521 |
| 515, 229, 324, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 515 x 229 x 324 x 521 = 39815799480
Therefore, the lowest common multiple of 515,458,648,521 is 39815799480.
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.
515 x 458 x 648 x 521 = 79631598960
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.
515 : 1, 5, 103, 515
458 : 1, 2, 229, 458
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,458,648,521, is 1.
Now, the common factors can be found like this.
515:5x 103
458:2x 229
648:2x 2x 2x 3x 3x 3x 3
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 79631598960/(1x2)
LCM = 79631598960/2
LCM = 39815799480
Thus, we can understand that the LCM of 515,458,648,521 is 39815799480.
