Given numbers are 980,999,860,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,999,860,980 is 42097860.
Find LCM of 980,999,860,980 with Prime Factorization
| 2 | 980, 999, 860, 980 |
| 2 | 490, 999, 430, 490 |
| 5 | 245, 999, 215, 245 |
| 7 | 49, 999, 43, 49 |
| 7 | 7, 999, 43, 7 |
| 1, 999, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 7 x 1 x 999 x 43 x 1 = 42097860
Therefore, the lowest common multiple of 980,999,860,980 is 42097860.
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.
980 x 999 x 860 x 980 = 825118056000
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
999 : 1, 3, 9, 27, 37, 111, 333, 999
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,999,860,980, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
999:3x 3x 3x 37
860:2x 2x 5x 43
980:2x 2x 5x 7x 7
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 2x 2x 5x 5x 7x 7 = 19600
Therefore, the value for common factors is 19600.
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 = 825118056000/(1x19600)
LCM = 825118056000/19600
LCM = 42097860
Thus, we can understand that the LCM of 980,999,860,980 is 42097860.
