Given numbers are 111,989,740,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 111,989,740,215 is 2195580.
Find LCM of 111,989,740,215 with Prime Factorization
| 5 | 111, 989, 740, 215 |
| 37 | 111, 989, 148, 43 |
| 43 | 3, 989, 4, 43 |
| 3, 23, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 37 x 43 x 3 x 23 x 4 x 1 = 2195580
Therefore, the lowest common multiple of 111,989,740,215 is 2195580.
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.
111 x 989 x 740 x 215 = 17465838900
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.
111 : 1, 3, 37, 111
989 : 1, 23, 43, 989
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,989,740,215, is 1.
Now, the common factors can be found like this.
111:3x 37
989:23x 43
740:2x 2x 5x 37
215:5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 37x 43 = 7955
Therefore, the value for common factors is 7955.
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 = 17465838900/(1x7955)
LCM = 17465838900/7955
LCM = 2195580
Thus, we can understand that the LCM of 111,989,740,215 is 2195580.
