Given numbers are 249,721,955,627,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,721,955,627,642 is 7668281421570.
Find LCM of 249,721,955,627,642 with Prime Factorization
| 3 | 249, 721, 955, 627, 642 |
| 83, 721, 955, 209, 214 |
Multiply the prime numbers at the bottom and the left side.
3 x 83 x 721 x 955 x 209 x 214 = 7668281421570
Therefore, the lowest common multiple of 249,721,955,627,642 is 7668281421570.
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.
249 x 721 x 955 x 627 x 642 = 69014532794130
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.
249 : 1, 3, 83, 249
721 : 1, 7, 103, 721
955 : 1, 5, 191, 955
627 : 1, 3, 11, 19, 33, 57, 209, 627
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,721,955,627,642, is 1.
Now, the common factors can be found like this.
249:3x 83
721:7x 103
955:5x 191
627:3x 11x 19
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 69014532794130/(1x9)
LCM = 69014532794130/9
LCM = 7668281421570
Thus, we can understand that the LCM of 249,721,955,627,642 is 7668281421570.
