Given numbers are 446,221,663,148
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 446,221,663,148 is 21881652.
Find LCM of 446,221,663,148 with Prime Factorization
| 2 | 446, 221, 663, 148 |
| 13 | 223, 221, 663, 74 |
| 17 | 223, 17, 51, 74 |
| 223, 1, 3, 74 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 223 x 1 x 3 x 74 = 21881652
Therefore, the lowest common multiple of 446,221,663,148 is 21881652.
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.
446 x 221 x 663 x 148 = 9671690184
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.
446 : 1, 2, 223, 446
221 : 1, 13, 17, 221
663 : 1, 3, 13, 17, 39, 51, 221, 663
148 : 1, 2, 4, 37, 74, 148
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,221,663,148, is 1.
Now, the common factors can be found like this.
446:2x 223
221:13x 17
663:3x 13x 17
148:2x 2x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 9671690184/(1x442)
LCM = 9671690184/442
LCM = 21881652
Thus, we can understand that the LCM of 446,221,663,148 is 21881652.
