The LCM of 973,195,819,443 is 252157815.
Find LCM of 973,195,819,443 with Prime Factorization
| 3 | 973, 195, 819, 443 |
| 7 | 973, 65, 273, 443 |
| 13 | 139, 65, 39, 443 |
| 139, 5, 3, 443 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 139 x 5 x 3 x 443 = 252157815
Therefore, the lowest common multiple of 973,195,819,443 is 252157815.
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.
973 x 195 x 819 x 443 = 68839083495
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.
973 : 1, 7, 139, 973
195 : 1, 3, 5, 13, 15, 39, 65, 195
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
443 : 1, 443
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,195,819,443, is 1.
Now, the common factors can be found like this.
973:7x 139
195:3x 5x 13
819:3x 3x 7x 13
443:443
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 13 = 273
Therefore, the value for common factors is 273.
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 = 68839083495/(1x273)
LCM = 68839083495/273
LCM = 252157815
Thus, we can understand that the LCM of 973,195,819,443 is 252157815.
