Given numbers are 995,357,768,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 995,357,768,105 is 90935040.
Find LCM of 995,357,768,105 with Prime Factorization
| 3 | 995, 357, 768, 105 |
| 5 | 995, 119, 256, 35 |
| 7 | 199, 119, 256, 7 |
| 199, 17, 256, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 199 x 17 x 256 x 1 = 90935040
Therefore, the lowest common multiple of 995,357,768,105 is 90935040.
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.
995 x 357 x 768 x 105 = 28644537600
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.
995 : 1, 5, 199, 995
357 : 1, 3, 7, 17, 21, 51, 119, 357
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 995,357,768,105, is 1.
Now, the common factors can be found like this.
995:5x 199
357:3x 7x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
105:3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 28644537600/(1x315)
LCM = 28644537600/315
LCM = 90935040
Thus, we can understand that the LCM of 995,357,768,105 is 90935040.
