Given numbers are 403,299,979,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,299,979,545 is 4945521295.
Find LCM of 403,299,979,545 with Prime Factorization
| 13 | 403, 299, 979, 545 |
| 31, 23, 979, 545 |
Multiply the prime numbers at the bottom and the left side.
13 x 31 x 23 x 979 x 545 = 4945521295
Therefore, the lowest common multiple of 403,299,979,545 is 4945521295.
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.
403 x 299 x 979 x 545 = 64291776835
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.
403 : 1, 13, 31, 403
299 : 1, 13, 23, 299
979 : 1, 11, 89, 979
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,299,979,545, is 1.
Now, the common factors can be found like this.
403:13x 31
299:13x 23
979:11x 89
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 64291776835/(1x13)
LCM = 64291776835/13
LCM = 4945521295
Thus, we can understand that the LCM of 403,299,979,545 is 4945521295.
