Given numbers are 474,345,611,455,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,345,611,455,915 is 14221495470.
Find LCM of 474,345,611,455,915 with Prime Factorization
| 3 | 474, 345, 611, 455, 915 |
| 5 | 158, 115, 611, 455, 305 |
| 13 | 158, 23, 611, 91, 61 |
| 158, 23, 47, 7, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 158 x 23 x 47 x 7 x 61 = 14221495470
Therefore, the lowest common multiple of 474,345,611,455,915 is 14221495470.
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.
474 x 345 x 611 x 455 x 915 = 41597874249750
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
345 : 1, 3, 5, 15, 23, 69, 115, 345
611 : 1, 13, 47, 611
455 : 1, 5, 7, 13, 35, 65, 91, 455
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,345,611,455,915, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
345:3x 5x 23
611:13x 47
455:5x 7x 13
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 13 = 2925
Therefore, the value for common factors is 2925.
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 = 41597874249750/(1x2925)
LCM = 41597874249750/2925
LCM = 14221495470
Thus, we can understand that the LCM of 474,345,611,455,915 is 14221495470.
