Given numbers are 90,88,31,69,713
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 90,88,31,69,713 is 2823480.
Find LCM of 90,88,31,69,713 with Prime Factorization
| 2 | 90, 88, 31, 69, 713 |
| 3 | 45, 44, 31, 69, 713 |
| 23 | 15, 44, 31, 23, 713 |
| 31 | 15, 44, 31, 1, 31 |
| 15, 44, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 31 x 15 x 44 x 1 x 1 x 1 = 2823480
Therefore, the lowest common multiple of 90,88,31,69,713 is 2823480.
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.
90 x 88 x 31 x 69 x 713 = 12078847440
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.
90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
88 : 1, 2, 4, 8, 11, 22, 44, 88
31 : 1, 31
69 : 1, 3, 23, 69
713 : 1, 23, 31, 713
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 90,88,31,69,713, is 1.
Now, the common factors can be found like this.
90:2x 3x 3x 5
88:2x 2x 2x 11
31:31
69:3x 23
713:23x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23x 31 = 4278
Therefore, the value for common factors is 4278.
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 = 12078847440/(1x4278)
LCM = 12078847440/4278
LCM = 2823480
Thus, we can understand that the LCM of 90,88,31,69,713 is 2823480.
