Given numbers are 315,668,991,844,867
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,668,991,844,867 is 12715720369380.
Find LCM of 315,668,991,844,867 with Prime Factorization
| 2 | 315, 668, 991, 844, 867 |
| 2 | 315, 334, 991, 422, 867 |
| 3 | 315, 167, 991, 211, 867 |
| 105, 167, 991, 211, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 105 x 167 x 991 x 211 x 289 = 12715720369380
Therefore, the lowest common multiple of 315,668,991,844,867 is 12715720369380.
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.
315 x 668 x 991 x 844 x 867 = 152588644432560
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
668 : 1, 2, 4, 167, 334, 668
991 : 1, 991
844 : 1, 2, 4, 211, 422, 844
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,668,991,844,867, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
668:2x 2x 167
991:991
844:2x 2x 211
867:3x 17x 17
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 3 = 12
Therefore, the value for common factors is 12.
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 = 152588644432560/(1x12)
LCM = 152588644432560/12
LCM = 12715720369380
Thus, we can understand that the LCM of 315,668,991,844,867 is 12715720369380.
