The LCM of 287,315,357,995,988 is 43167147660.
Find LCM of 287,315,357,995,988 with Prime Factorization
| 3 | 287, 315, 357, 995, 988 |
| 5 | 287, 105, 119, 995, 988 |
| 7 | 287, 21, 119, 199, 988 |
| 41, 3, 17, 199, 988 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 41 x 3 x 17 x 199 x 988 = 43167147660
Therefore, the lowest common multiple of 287,315,357,995,988 is 43167147660.
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 315 x 357 x 995 x 988 = 31727853530100
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
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
357 : 1, 3, 7, 17, 21, 51, 119, 357
995 : 1, 5, 199, 995
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,315,357,995,988, is 1.
Now, the common factors can be found like this.
287:7x 41
315:3x 3x 5x 7
357:3x 7x 17
995:5x 199
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 7 = 735
Therefore, the value for common factors is 735.
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 = 31727853530100/(1x735)
LCM = 31727853530100/735
LCM = 43167147660
Thus, we can understand that the LCM of 287,315,357,995,988 is 43167147660.
