The LCM of 715,561,252,918 is 9189180.
Find LCM of 715,561,252,918 with Prime Factorization
| 2 | 715, 561, 252, 918 |
| 3 | 715, 561, 126, 459 |
| 3 | 715, 187, 42, 153 |
| 11 | 715, 187, 14, 51 |
| 17 | 65, 17, 14, 51 |
| 65, 1, 14, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 17 x 65 x 1 x 14 x 3 = 9189180
Therefore, the lowest common multiple of 715,561,252,918 is 9189180.
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.
715 x 561 x 252 x 918 = 92792339640
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
561 : 1, 3, 11, 17, 33, 51, 187, 561
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,561,252,918, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
561:3x 11x 17
252:2x 2x 3x 3x 7
918:2x 3x 3x 3x 17
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 11x 17 = 10098
Therefore, the value for common factors is 10098.
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 = 92792339640/(1x10098)
LCM = 92792339640/10098
LCM = 9189180
Thus, we can understand that the LCM of 715,561,252,918 is 9189180.
