Given numbers are 842,802,918,707,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,802,918,707,447 is 16325813533554.
Find LCM of 842,802,918,707,447 with Prime Factorization
| 2 | 842, 802, 918, 707, 447 |
| 3 | 421, 401, 459, 707, 447 |
| 421, 401, 153, 707, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 421 x 401 x 153 x 707 x 149 = 16325813533554
Therefore, the lowest common multiple of 842,802,918,707,447 is 16325813533554.
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.
842 x 802 x 918 x 707 x 447 = 195909762402648
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.
842 : 1, 2, 421, 842
802 : 1, 2, 401, 802
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
707 : 1, 7, 101, 707
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,802,918,707,447, is 1.
Now, the common factors can be found like this.
842:2x 421
802:2x 401
918:2x 3x 3x 3x 17
707:7x 101
447:3x 149
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 3 = 12
Therefore, the value for common factors is 12.
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 = 195909762402648/(1x12)
LCM = 195909762402648/12
LCM = 16325813533554
Thus, we can understand that the LCM of 842,802,918,707,447 is 16325813533554.
