Given numbers are 721,721,391,726
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,721,391,726 is 204667386.
Find LCM of 721,721,391,726 with Prime Factorization
7 | 721, 721, 391, 726 |
103 | 103, 103, 391, 726 |
1, 1, 391, 726 |
Multiply the prime numbers at the bottom and the left side.
7 x 103 x 1 x 1 x 391 x 726 = 204667386
Therefore, the lowest common multiple of 721,721,391,726 is 204667386.
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 721 x 391 x 726 = 147565185306
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
721 : 1, 7, 103, 721
391 : 1, 17, 23, 391
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,721,391,726, is 1.
Now, the common factors can be found like this.
721:7x 103
721:7x 103
391:17x 23
726:2x 3x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 103 = 721
Therefore, the value for common factors is 721.
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 = 147565185306/(1x721)
LCM = 147565185306/721
LCM = 204667386
Thus, we can understand that the LCM of 721,721,391,726 is 204667386.
