Given numbers are 898,770,638,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,770,638,989 is 9915882130.
Find LCM of 898,770,638,989 with Prime Factorization
| 2 | 898, 770, 638, 989 |
| 11 | 449, 385, 319, 989 |
| 449, 35, 29, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 449 x 35 x 29 x 989 = 9915882130
Therefore, the lowest common multiple of 898,770,638,989 is 9915882130.
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.
898 x 770 x 638 x 989 = 436298813720
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.
898 : 1, 2, 449, 898
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
638 : 1, 2, 11, 22, 29, 58, 319, 638
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,770,638,989, is 1.
Now, the common factors can be found like this.
898:2x 449
770:2x 5x 7x 11
638:2x 11x 29
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.
2x 2x 11 = 44
Therefore, the value for common factors is 44.
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 = 436298813720/(1x44)
LCM = 436298813720/44
LCM = 9915882130
Thus, we can understand that the LCM of 898,770,638,989 is 9915882130.
