The LCM of 398,462,319,280,443 is 23622549720.
Find LCM of 398,462,319,280,443 with Prime Factorization
| 2 | 398, 462, 319, 280, 443 |
| 7 | 199, 231, 319, 140, 443 |
| 11 | 199, 33, 319, 20, 443 |
| 199, 3, 29, 20, 443 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 199 x 3 x 29 x 20 x 443 = 23622549720
Therefore, the lowest common multiple of 398,462,319,280,443 is 23622549720.
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.
398 x 462 x 319 x 280 x 443 = 7275745313760
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.
398 : 1, 2, 199, 398
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
319 : 1, 11, 29, 319
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
443 : 1, 443
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,462,319,280,443, is 1.
Now, the common factors can be found like this.
398:2x 199
462:2x 3x 7x 11
319:11x 29
280:2x 2x 2x 5x 7
443:443
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 7275745313760/(1x308)
LCM = 7275745313760/308
LCM = 23622549720
Thus, we can understand that the LCM of 398,462,319,280,443 is 23622549720.
