Given numbers are 287,876,672,706
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,876,672,706 is 709987488.
Find LCM of 287,876,672,706 with Prime Factorization
| 2 | 287, 876, 672, 706 |
| 2 | 287, 438, 336, 353 |
| 3 | 287, 219, 168, 353 |
| 7 | 287, 73, 56, 353 |
| 41, 73, 8, 353 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 41 x 73 x 8 x 353 = 709987488
Therefore, the lowest common multiple of 287,876,672,706 is 709987488.
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 876 x 672 x 706 = 119277897984
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
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
706 : 1, 2, 353, 706
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,876,672,706, is 1.
Now, the common factors can be found like this.
287:7x 41
876:2x 2x 3x 73
672:2x 2x 2x 2x 2x 3x 7
706:2x 353
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 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 119277897984/(1x168)
LCM = 119277897984/168
LCM = 709987488
Thus, we can understand that the LCM of 287,876,672,706 is 709987488.
