Find LCM of 981,722,949,909,404 with Prime Factorization
| 2 | 981, 722, 949, 909, 404 |
| 3 | 981, 361, 949, 909, 202 |
| 3 | 327, 361, 949, 303, 202 |
| 101 | 109, 361, 949, 101, 202 |
| 109, 361, 949, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 101 x 109 x 361 x 949 x 1 x 2 = 135776242836
Therefore, the lowest common multiple of 981,722,949,909,404 is 135776242836.
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.
981 x 722 x 949 x 909 x 404 = 246841209475848
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.
981 : 1, 3, 9, 109, 327, 981
722 : 1, 2, 19, 38, 361, 722
949 : 1, 13, 73, 949
909 : 1, 3, 9, 101, 303, 909
404 : 1, 2, 4, 101, 202, 404
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,722,949,909,404, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
722:2x 19x 19
949:13x 73
909:3x 3x 101
404:2x 2x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 101 = 1818
Therefore, the value for common factors is 1818.
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 = 246841209475848/(1x1818)
LCM = 246841209475848/1818
LCM = 135776242836
Thus, we can understand that the LCM of 981,722,949,909,404 is 135776242836.
