Given numbers are 267,721,341,515,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 267,721,341,515,981 is 107329390245.
Find LCM of 267,721,341,515,981 with Prime Factorization
| 3 | 267, 721, 341, 515, 981 |
| 103 | 89, 721, 341, 515, 327 |
| 89, 7, 341, 5, 327 |
Multiply the prime numbers at the bottom and the left side.
3 x 103 x 89 x 7 x 341 x 5 x 327 = 107329390245
Therefore, the lowest common multiple of 267,721,341,515,981 is 107329390245.
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.
267 x 721 x 341 x 515 x 981 = 33164781585705
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.
267 : 1, 3, 89, 267
721 : 1, 7, 103, 721
341 : 1, 11, 31, 341
515 : 1, 5, 103, 515
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 267,721,341,515,981, is 1.
Now, the common factors can be found like this.
267:3x 89
721:7x 103
341:11x 31
515:5x 103
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 103 = 309
Therefore, the value for common factors is 309.
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 = 33164781585705/(1x309)
LCM = 33164781585705/309
LCM = 107329390245
Thus, we can understand that the LCM of 267,721,341,515,981 is 107329390245.
