Given numbers are 107,985,788,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 107,985,788,100 is 2107900.
Find LCM of 107,985,788,100 with Prime Factorization
| 2 | 107, 985, 788, 100 |
| 2 | 107, 985, 394, 50 |
| 5 | 107, 985, 197, 25 |
| 197 | 107, 197, 197, 5 |
| 107, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 197 x 107 x 1 x 1 x 5 = 2107900
Therefore, the lowest common multiple of 107,985,788,100 is 2107900.
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.
107 x 985 x 788 x 100 = 8305126000
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.
107 : 1, 107
985 : 1, 5, 197, 985
788 : 1, 2, 4, 197, 394, 788
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,985,788,100, is 1.
Now, the common factors can be found like this.
107:107
985:5x 197
788:2x 2x 197
100:2x 2x 5x 5
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 5x 197 = 3940
Therefore, the value for common factors is 3940.
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 = 8305126000/(1x3940)
LCM = 8305126000/3940
LCM = 2107900
Thus, we can understand that the LCM of 107,985,788,100 is 2107900.
