Given numbers are 428,924,714,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,924,714,979 is 149587284.
Find LCM of 428,924,714,979 with Prime Factorization
| 2 | 428, 924, 714, 979 |
| 2 | 214, 462, 357, 979 |
| 3 | 107, 231, 357, 979 |
| 7 | 107, 77, 119, 979 |
| 11 | 107, 11, 17, 979 |
| 107, 1, 17, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 107 x 1 x 17 x 89 = 149587284
Therefore, the lowest common multiple of 428,924,714,979 is 149587284.
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.
428 x 924 x 714 x 979 = 276437300832
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.
428 : 1, 2, 4, 107, 214, 428
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,924,714,979, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
924:2x 2x 3x 7x 11
714:2x 3x 7x 17
979:11x 89
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 3x 7x 11 = 1848
Therefore, the value for common factors is 1848.
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 = 276437300832/(1x1848)
LCM = 276437300832/1848
LCM = 149587284
Thus, we can understand that the LCM of 428,924,714,979 is 149587284.
