Given numbers are 641,874,115,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 641,874,115,187 is 523818790.
Find LCM of 641,874,115,187 with Prime Factorization
| 23 | 641, 874, 115, 187 |
| 641, 38, 5, 187 |
Multiply the prime numbers at the bottom and the left side.
23 x 641 x 38 x 5 x 187 = 523818790
Therefore, the lowest common multiple of 641,874,115,187 is 523818790.
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.
641 x 874 x 115 x 187 = 12047832170
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.
641 : 1, 641
874 : 1, 2, 19, 23, 38, 46, 437, 874
115 : 1, 5, 23, 115
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,874,115,187, is 1.
Now, the common factors can be found like this.
641:641
874:2x 19x 23
115:5x 23
187:11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 12047832170/(1x23)
LCM = 12047832170/23
LCM = 523818790
Thus, we can understand that the LCM of 641,874,115,187 is 523818790.
