Given numbers are 896,749,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 896,749,989 is 94817408.
Find LCM of 896,749,989 with Prime Factorization
| 7 | 896, 749, 989 |
| 128, 107, 989 |
Multiply the prime numbers at the bottom and the left side.
7 x 128 x 107 x 989 = 94817408
Therefore, the lowest common multiple of 896,749,989 is 94817408.
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.
896 x 749 x 989 = 663721856
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
749 : 1, 7, 107, 749
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,749,989, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
749:7x 107
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 663721856/(1x7)
LCM = 663721856/7
LCM = 94817408
Thus, we can understand that the LCM of 896,749,989 is 94817408.
