Given numbers are 143,242,820,385,995
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,242,820,385,995 is 1796774980.
Find LCM of 143,242,820,385,995 with Prime Factorization
| 2 | 143, 242, 820, 385, 995 |
| 5 | 143, 121, 410, 385, 995 |
| 11 | 143, 121, 82, 77, 199 |
| 13, 11, 82, 7, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 11 x 82 x 7 x 199 = 1796774980
Therefore, the lowest common multiple of 143,242,820,385,995 is 1796774980.
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.
143 x 242 x 820 x 385 x 995 = 10870488629000
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.
143 : 1, 11, 13, 143
242 : 1, 2, 11, 22, 121, 242
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
385 : 1, 5, 7, 11, 35, 55, 77, 385
995 : 1, 5, 199, 995
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,242,820,385,995, is 1.
Now, the common factors can be found like this.
143:11x 13
242:2x 11x 11
820:2x 2x 5x 41
385:5x 7x 11
995:5x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11x 11 = 6050
Therefore, the value for common factors is 6050.
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 = 10870488629000/(1x6050)
LCM = 10870488629000/6050
LCM = 1796774980
Thus, we can understand that the LCM of 143,242,820,385,995 is 1796774980.
