Given numbers are 915,581,880,923,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,581,880,923,781 is 86359793520.
Find LCM of 915,581,880,923,781 with Prime Factorization
| 5 | 915, 581, 880, 923, 781 |
| 11 | 183, 581, 176, 923, 781 |
| 71 | 183, 581, 16, 923, 71 |
| 183, 581, 16, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 71 x 183 x 581 x 16 x 13 x 1 = 86359793520
Therefore, the lowest common multiple of 915,581,880,923,781 is 86359793520.
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.
915 x 581 x 880 x 923 x 781 = 337234993695600
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
581 : 1, 7, 83, 581
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
923 : 1, 13, 71, 923
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,581,880,923,781, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
581:7x 83
880:2x 2x 2x 2x 5x 11
923:13x 71
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 71 = 3905
Therefore, the value for common factors is 3905.
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 = 337234993695600/(1x3905)
LCM = 337234993695600/3905
LCM = 86359793520
Thus, we can understand that the LCM of 915,581,880,923,781 is 86359793520.
