Given numbers are 721,511,199,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,511,199,286 is 2995554562.
Find LCM of 721,511,199,286 with Prime Factorization
| 7 | 721, 511, 199, 286 |
| 103, 73, 199, 286 |
Multiply the prime numbers at the bottom and the left side.
7 x 103 x 73 x 199 x 286 = 2995554562
Therefore, the lowest common multiple of 721,511,199,286 is 2995554562.
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.
721 x 511 x 199 x 286 = 20968881934
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.
721 : 1, 7, 103, 721
511 : 1, 7, 73, 511
199 : 1, 199
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,511,199,286, is 1.
Now, the common factors can be found like this.
721:7x 103
511:7x 73
199:199
286:2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 20968881934/(1x7)
LCM = 20968881934/7
LCM = 2995554562
Thus, we can understand that the LCM of 721,511,199,286 is 2995554562.
