Given numbers are 989,900,872,993,853
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,900,872,993,853 is 54786343937400.
Find LCM of 989,900,872,993,853 with Prime Factorization
| 2 | 989, 900, 872, 993, 853 |
| 2 | 989, 450, 436, 993, 853 |
| 3 | 989, 225, 218, 993, 853 |
| 989, 75, 218, 331, 853 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 989 x 75 x 218 x 331 x 853 = 54786343937400
Therefore, the lowest common multiple of 989,900,872,993,853 is 54786343937400.
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 900 x 872 x 993 x 853 = 657436127248800
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
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
872 : 1, 2, 4, 8, 109, 218, 436, 872
993 : 1, 3, 331, 993
853 : 1, 853
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,900,872,993,853, is 1.
Now, the common factors can be found like this.
989:23x 43
900:2x 2x 3x 3x 5x 5
872:2x 2x 2x 109
993:3x 331
853:853
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 3 = 12
Therefore, the value for common factors is 12.
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 = 657436127248800/(1x12)
LCM = 657436127248800/12
LCM = 54786343937400
Thus, we can understand that the LCM of 989,900,872,993,853 is 54786343937400.
