Given numbers are 308,143,442,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,143,442,842 is 28656628.
Find LCM of 308,143,442,842 with Prime Factorization
| 2 | 308, 143, 442, 842 |
| 11 | 154, 143, 221, 421 |
| 13 | 14, 13, 221, 421 |
| 14, 1, 17, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 14 x 1 x 17 x 421 = 28656628
Therefore, the lowest common multiple of 308,143,442,842 is 28656628.
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.
308 x 143 x 442 x 842 = 16391591216
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
143 : 1, 11, 13, 143
442 : 1, 2, 13, 17, 26, 34, 221, 442
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,143,442,842, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
143:11x 13
442:2x 13x 17
842:2x 421
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 11x 13 = 572
Therefore, the value for common factors is 572.
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 = 16391591216/(1x572)
LCM = 16391591216/572
LCM = 28656628
Thus, we can understand that the LCM of 308,143,442,842 is 28656628.
