Given numbers are 221,979,725,480,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,979,725,480,969 is 286113141600.
Find LCM of 221,979,725,480,969 with Prime Factorization
| 3 | 221, 979, 725, 480, 969 |
| 5 | 221, 979, 725, 160, 323 |
| 17 | 221, 979, 145, 32, 323 |
| 13, 979, 145, 32, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 13 x 979 x 145 x 32 x 19 = 286113141600
Therefore, the lowest common multiple of 221,979,725,480,969 is 286113141600.
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.
221 x 979 x 725 x 480 x 969 = 72958851108000
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.
221 : 1, 13, 17, 221
979 : 1, 11, 89, 979
725 : 1, 5, 25, 29, 145, 725
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,979,725,480,969, is 1.
Now, the common factors can be found like this.
221:13x 17
979:11x 89
725:5x 5x 29
480:2x 2x 2x 2x 2x 3x 5
969:3x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 17 = 255
Therefore, the value for common factors is 255.
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 = 72958851108000/(1x255)
LCM = 72958851108000/255
LCM = 286113141600
Thus, we can understand that the LCM of 221,979,725,480,969 is 286113141600.
