Given numbers are 119,231,621,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 119,231,621,979 is 72347121.
Find LCM of 119,231,621,979 with Prime Factorization
| 3 | 119, 231, 621, 979 |
| 7 | 119, 77, 207, 979 |
| 11 | 17, 11, 207, 979 |
| 17, 1, 207, 89 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 17 x 1 x 207 x 89 = 72347121
Therefore, the lowest common multiple of 119,231,621,979 is 72347121.
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.
119 x 231 x 621 x 979 = 16712184951
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.
119 : 1, 7, 17, 119
231 : 1, 3, 7, 11, 21, 33, 77, 231
621 : 1, 3, 9, 23, 27, 69, 207, 621
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 119,231,621,979, is 1.
Now, the common factors can be found like this.
119:7x 17
231:3x 7x 11
621:3x 3x 3x 23
979:11x 89
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 11 = 231
Therefore, the value for common factors is 231.
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 = 16712184951/(1x231)
LCM = 16712184951/231
LCM = 72347121
Thus, we can understand that the LCM of 119,231,621,979 is 72347121.
