Given numbers are 287,835,686,878,630
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,835,686,878,630 is 92790064710.
Find LCM of 287,835,686,878,630 with Prime Factorization
| 2 | 287, 835, 686, 878, 630 |
| 5 | 287, 835, 343, 439, 315 |
| 7 | 287, 167, 343, 439, 63 |
| 41, 167, 49, 439, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 41 x 167 x 49 x 439 x 9 = 92790064710
Therefore, the lowest common multiple of 287,835,686,878,630 is 92790064710.
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.
287 x 835 x 686 x 878 x 630 = 90934263415800
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.
287 : 1, 7, 41, 287
835 : 1, 5, 167, 835
686 : 1, 2, 7, 14, 49, 98, 343, 686
878 : 1, 2, 439, 878
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,835,686,878,630, is 1.
Now, the common factors can be found like this.
287:7x 41
835:5x 167
686:2x 7x 7x 7
878:2x 439
630:2x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 7x 7 = 980
Therefore, the value for common factors is 980.
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 = 90934263415800/(1x980)
LCM = 90934263415800/980
LCM = 92790064710
Thus, we can understand that the LCM of 287,835,686,878,630 is 92790064710.
