Find LCM of 679,974,873,855,147 with Prime Factorization
| 3 | 679, 974, 873, 855, 147 |
| 3 | 679, 974, 291, 285, 49 |
| 7 | 679, 974, 97, 95, 49 |
| 97 | 97, 974, 97, 95, 7 |
| 1, 974, 1, 95, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 97 x 1 x 974 x 1 x 95 x 7 = 3958155810
Therefore, the lowest common multiple of 679,974,873,855,147 is 3958155810.
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.
679 x 974 x 873 x 855 x 147 = 72564870464730
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.
679 : 1, 7, 97, 679
974 : 1, 2, 487, 974
873 : 1, 3, 9, 97, 291, 873
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,974,873,855,147, is 1.
Now, the common factors can be found like this.
679:7x 97
974:2x 487
873:3x 3x 97
855:3x 3x 5x 19
147:3x 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.
3x 3x 3x 7x 97 = 18333
Therefore, the value for common factors is 18333.
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 = 72564870464730/(1x18333)
LCM = 72564870464730/18333
LCM = 3958155810
Thus, we can understand that the LCM of 679,974,873,855,147 is 3958155810.
