Given numbers are 894,429,285,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,429,285,915 is 740844390.
Find LCM of 894,429,285,915 with Prime Factorization
| 3 | 894, 429, 285, 915 |
| 5 | 298, 143, 95, 305 |
| 298, 143, 19, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 298 x 143 x 19 x 61 = 740844390
Therefore, the lowest common multiple of 894,429,285,915 is 740844390.
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.
894 x 429 x 285 x 915 = 100013992650
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
429 : 1, 3, 11, 13, 33, 39, 143, 429
285 : 1, 3, 5, 15, 19, 57, 95, 285
915 : 1, 3, 5, 15, 61, 183, 305, 915
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,429,285,915, is 3.
Now, the common factors can be found like this.
894:2x 3x 149
429:3x 11x 13
285:3x 5x 19
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 5 = 45
Therefore, the value for common factors is 45.
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 = 100013992650/(3x45)
LCM = 100013992650/135
LCM = 740844390
Thus, we can understand that the LCM of 894,429,285,915 is 740844390.
