Given numbers are 561,179,710,358
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,179,710,358 is 71297490.
Find LCM of 561,179,710,358 with Prime Factorization
| 2 | 561, 179, 710, 358 |
| 179 | 561, 179, 355, 179 |
| 561, 1, 355, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 179 x 561 x 1 x 355 x 1 = 71297490
Therefore, the lowest common multiple of 561,179,710,358 is 71297490.
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.
561 x 179 x 710 x 358 = 25524501420
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
179 : 1, 179
710 : 1, 2, 5, 10, 71, 142, 355, 710
358 : 1, 2, 179, 358
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,179,710,358, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
179:179
710:2x 5x 71
358:2x 179
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 179 = 358
Therefore, the value for common factors is 358.
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 = 25524501420/(1x358)
LCM = 25524501420/358
LCM = 71297490
Thus, we can understand that the LCM of 561,179,710,358 is 71297490.
