Given numbers are 397,715,221,132,712
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,715,221,132,712 is 10307342760.
Find LCM of 397,715,221,132,712 with Prime Factorization
| 2 | 397, 715, 221, 132, 712 |
| 2 | 397, 715, 221, 66, 356 |
| 11 | 397, 715, 221, 33, 178 |
| 13 | 397, 65, 221, 3, 178 |
| 397, 5, 17, 3, 178 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 397 x 5 x 17 x 3 x 178 = 10307342760
Therefore, the lowest common multiple of 397,715,221,132,712 is 10307342760.
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.
397 x 715 x 221 x 132 x 712 = 5895800058720
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.
397 : 1, 397
715 : 1, 5, 11, 13, 55, 65, 143, 715
221 : 1, 13, 17, 221
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
712 : 1, 2, 4, 8, 89, 178, 356, 712
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,715,221,132,712, is 1.
Now, the common factors can be found like this.
397:397
715:5x 11x 13
221:13x 17
132:2x 2x 3x 11
712:2x 2x 2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11x 13 = 572
Therefore, the value for common factors is 572.
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 = 5895800058720/(1x572)
LCM = 5895800058720/572
LCM = 10307342760
Thus, we can understand that the LCM of 397,715,221,132,712 is 10307342760.
