Given numbers are 723,726,370,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,726,370,990 is 97106130.
Find LCM of 723,726,370,990 with Prime Factorization
| 2 | 723, 726, 370, 990 |
| 3 | 723, 363, 185, 495 |
| 5 | 241, 121, 185, 165 |
| 11 | 241, 121, 37, 33 |
| 241, 11, 37, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 241 x 11 x 37 x 3 = 97106130
Therefore, the lowest common multiple of 723,726,370,990 is 97106130.
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.
723 x 726 x 370 x 990 = 192270137400
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.
723 : 1, 3, 241, 723
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
370 : 1, 2, 5, 10, 37, 74, 185, 370
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,726,370,990, is 1.
Now, the common factors can be found like this.
723:3x 241
726:2x 3x 11x 11
370:2x 5x 37
990:2x 3x 3x 5x 11
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 3x 3x 5x 11 = 1980
Therefore, the value for common factors is 1980.
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 = 192270137400/(1x1980)
LCM = 192270137400/1980
LCM = 97106130
Thus, we can understand that the LCM of 723,726,370,990 is 97106130.
