Given numbers are 853,642,642,249,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,642,642,249,957 is 14499493602.
Find LCM of 853,642,642,249,957 with Prime Factorization
| 2 | 853, 642, 642, 249, 957 |
| 3 | 853, 321, 321, 249, 957 |
| 107 | 853, 107, 107, 83, 319 |
| 853, 1, 1, 83, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 853 x 1 x 1 x 83 x 319 = 14499493602
Therefore, the lowest common multiple of 853,642,642,249,957 is 14499493602.
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.
853 x 642 x 642 x 249 x 957 = 83778074032356
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.
853 : 1, 853
642 : 1, 2, 3, 6, 107, 214, 321, 642
642 : 1, 2, 3, 6, 107, 214, 321, 642
249 : 1, 3, 83, 249
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,642,642,249,957, is 1.
Now, the common factors can be found like this.
853:853
642:2x 3x 107
642:2x 3x 107
249:3x 83
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 107 = 5778
Therefore, the value for common factors is 5778.
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 = 83778074032356/(1x5778)
LCM = 83778074032356/5778
LCM = 14499493602
Thus, we can understand that the LCM of 853,642,642,249,957 is 14499493602.
