Given numbers are 290,654,849,836,142
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,654,849,836,142 is 796465221420.
Find LCM of 290,654,849,836,142 with Prime Factorization
| 2 | 290, 654, 849, 836, 142 |
| 3 | 145, 327, 849, 418, 71 |
| 145, 109, 283, 418, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 145 x 109 x 283 x 418 x 71 = 796465221420
Therefore, the lowest common multiple of 290,654,849,836,142 is 796465221420.
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.
290 x 654 x 849 x 836 x 142 = 19115165314080
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
654 : 1, 2, 3, 6, 109, 218, 327, 654
849 : 1, 3, 283, 849
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
142 : 1, 2, 71, 142
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,654,849,836,142, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
654:2x 3x 109
849:3x 283
836:2x 2x 11x 19
142:2x 71
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 19115165314080/(1x24)
LCM = 19115165314080/24
LCM = 796465221420
Thus, we can understand that the LCM of 290,654,849,836,142 is 796465221420.
