Given numbers are 404,639,293,942,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 404,639,293,942,442 is 2624470948476.
Find LCM of 404,639,293,942,442 with Prime Factorization
| 2 | 404, 639, 293, 942, 442 |
| 3 | 202, 639, 293, 471, 221 |
| 202, 213, 293, 157, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 202 x 213 x 293 x 157 x 221 = 2624470948476
Therefore, the lowest common multiple of 404,639,293,942,442 is 2624470948476.
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.
404 x 639 x 293 x 942 x 442 = 31493651381712
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.
404 : 1, 2, 4, 101, 202, 404
639 : 1, 3, 9, 71, 213, 639
293 : 1, 293
942 : 1, 2, 3, 6, 157, 314, 471, 942
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,639,293,942,442, is 1.
Now, the common factors can be found like this.
404:2x 2x 101
639:3x 3x 71
293:293
942:2x 3x 157
442:2x 13x 17
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 3 = 12
Therefore, the value for common factors is 12.
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 = 31493651381712/(1x12)
LCM = 31493651381712/12
LCM = 2624470948476
Thus, we can understand that the LCM of 404,639,293,942,442 is 2624470948476.
