Given numbers are 895,708,285,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 895,708,285,642 is 1288230780.
Find LCM of 895,708,285,642 with Prime Factorization
| 2 | 895, 708, 285, 642 |
| 3 | 895, 354, 285, 321 |
| 5 | 895, 118, 95, 107 |
| 179, 118, 19, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 179 x 118 x 19 x 107 = 1288230780
Therefore, the lowest common multiple of 895,708,285,642 is 1288230780.
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.
895 x 708 x 285 x 642 = 115940770200
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.
895 : 1, 5, 179, 895
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
285 : 1, 3, 5, 15, 19, 57, 95, 285
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 895,708,285,642, is 1.
Now, the common factors can be found like this.
895:5x 179
708:2x 2x 3x 59
285:3x 5x 19
642:2x 3x 107
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 115940770200/(1x90)
LCM = 115940770200/90
LCM = 1288230780
Thus, we can understand that the LCM of 895,708,285,642 is 1288230780.
