Given numbers are 341,120,257,442,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 341,120,257,442,771 is 2324133240.
Find LCM of 341,120,257,442,771 with Prime Factorization
| 2 | 341, 120, 257, 442, 771 |
| 3 | 341, 60, 257, 221, 771 |
| 257 | 341, 20, 257, 221, 257 |
| 341, 20, 1, 221, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 257 x 341 x 20 x 1 x 221 x 1 = 2324133240
Therefore, the lowest common multiple of 341,120,257,442,771 is 2324133240.
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.
341 x 120 x 257 x 442 x 771 = 3583813456080
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.
341 : 1, 11, 31, 341
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
257 : 1, 257
442 : 1, 2, 13, 17, 26, 34, 221, 442
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 341,120,257,442,771, is 1.
Now, the common factors can be found like this.
341:11x 31
120:2x 2x 2x 3x 5
257:257
442:2x 13x 17
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 257 = 1542
Therefore, the value for common factors is 1542.
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 = 3583813456080/(1x1542)
LCM = 3583813456080/1542
LCM = 2324133240
Thus, we can understand that the LCM of 341,120,257,442,771 is 2324133240.
