Given numbers are 909,621,881,619
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,621,881,619 is 34204207419.
Find LCM of 909,621,881,619 with Prime Factorization
| 3 | 909, 621, 881, 619 |
| 3 | 303, 207, 881, 619 |
| 101, 69, 881, 619 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 101 x 69 x 881 x 619 = 34204207419
Therefore, the lowest common multiple of 909,621,881,619 is 34204207419.
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.
909 x 621 x 881 x 619 = 307837866771
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.
909 : 1, 3, 9, 101, 303, 909
621 : 1, 3, 9, 23, 27, 69, 207, 621
881 : 1, 881
619 : 1, 619
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,621,881,619, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
621:3x 3x 3x 23
881:881
619:619
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 307837866771/(1x9)
LCM = 307837866771/9
LCM = 34204207419
Thus, we can understand that the LCM of 909,621,881,619 is 34204207419.
