Given numbers are 440,915,601,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,915,601,805 is 7791195720.
Find LCM of 440,915,601,805 with Prime Factorization
| 5 | 440, 915, 601, 805 |
| 88, 183, 601, 161 |
Multiply the prime numbers at the bottom and the left side.
5 x 88 x 183 x 601 x 161 = 7791195720
Therefore, the lowest common multiple of 440,915,601,805 is 7791195720.
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.
440 x 915 x 601 x 805 = 194779893000
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
915 : 1, 3, 5, 15, 61, 183, 305, 915
601 : 1, 601
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,915,601,805, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
915:3x 5x 61
601:601
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 194779893000/(1x25)
LCM = 194779893000/25
LCM = 7791195720
Thus, we can understand that the LCM of 440,915,601,805 is 7791195720.
