Given numbers are 989,891,307,247,473
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,891,307,247,473 is 66820438971.
Find LCM of 989,891,307,247,473 with Prime Factorization
11 | 989, 891, 307, 247, 473 |
43 | 989, 81, 307, 247, 43 |
23, 81, 307, 247, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 43 x 23 x 81 x 307 x 247 x 1 = 66820438971
Therefore, the lowest common multiple of 989,891,307,247,473 is 66820438971.
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.
989 x 891 x 307 x 247 x 473 = 31606067633283
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.
989 : 1, 23, 43, 989
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
307 : 1, 307
247 : 1, 13, 19, 247
473 : 1, 11, 43, 473
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,891,307,247,473, is 1.
Now, the common factors can be found like this.
989:23x 43
891:3x 3x 3x 3x 11
307:307
247:13x 19
473:11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 43 = 473
Therefore, the value for common factors is 473.
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 = 31606067633283/(1x473)
LCM = 31606067633283/473
LCM = 66820438971
Thus, we can understand that the LCM of 989,891,307,247,473 is 66820438971.
