Given numbers are 8672,9872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8672,9872 is 5350624.
Find LCM of 8672,9872 with Prime Factorization
| 2 | 8672, 9872 |
| 2 | 4336, 4936 |
| 2 | 2168, 2468 |
| 2 | 1084, 1234 |
| 542, 617 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 542 x 617 = 5350624
Therefore, the lowest common multiple of 8672,9872 is 5350624.
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.
8672 x 9872 = 85609984
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.
8672 : 1, 2, 4, 8, 16, 32, 271, 542, 1084, 2168, 4336, 8672
9872 : 1, 2, 4, 8, 16, 617, 1234, 2468, 4936, 9872
16 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8672,9872, is 16.
Now, the common factors can be found like this.
8672:2x 2x 2x 2x 2x 271
9872:2x 2x 2x 2x 617
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 85609984/(16x1)
LCM = 85609984/16
LCM = 5350624
Thus, we can understand that the LCM of 8672,9872 is 5350624.
