Given numbers are 403,856,961,545,223
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,856,961,545,223 is 1299696262280.
Find LCM of 403,856,961,545,223 with Prime Factorization
| 31 | 403, 856, 961, 545, 223 |
| 13, 856, 31, 545, 223 |
Multiply the prime numbers at the bottom and the left side.
31 x 13 x 856 x 31 x 545 x 223 = 1299696262280
Therefore, the lowest common multiple of 403,856,961,545,223 is 1299696262280.
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 856 x 961 x 545 x 223 = 40290584130680
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
856 : 1, 2, 4, 8, 107, 214, 428, 856
961 : 1, 31, 961
545 : 1, 5, 109, 545
223 : 1, 223
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,856,961,545,223, is 1.
Now, the common factors can be found like this.
403:13x 31
856:2x 2x 2x 107
961:31x 31
545:5x 109
223:223
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31 = 31
Therefore, the value for common factors is 31.
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 = 40290584130680/(1x31)
LCM = 40290584130680/31
LCM = 1299696262280
Thus, we can understand that the LCM of 403,856,961,545,223 is 1299696262280.
