Given numbers are 118,421,961,928,404
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 118,421,961,928,404 is 2237313510112.
Find LCM of 118,421,961,928,404 with Prime Factorization
| 2 | 118, 421, 961, 928, 404 |
| 2 | 59, 421, 961, 464, 202 |
| 59, 421, 961, 232, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 59 x 421 x 961 x 232 x 101 = 2237313510112
Therefore, the lowest common multiple of 118,421,961,928,404 is 2237313510112.
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.
118 x 421 x 961 x 928 x 404 = 17898508080896
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.
118 : 1, 2, 59, 118
421 : 1, 421
961 : 1, 31, 961
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
404 : 1, 2, 4, 101, 202, 404
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 118,421,961,928,404, is 1.
Now, the common factors can be found like this.
118:2x 59
421:421
961:31x 31
928:2x 2x 2x 2x 2x 29
404:2x 2x 101
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 2 = 8
Therefore, the value for common factors is 8.
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 = 17898508080896/(1x8)
LCM = 17898508080896/8
LCM = 2237313510112
Thus, we can understand that the LCM of 118,421,961,928,404 is 2237313510112.
