Given numbers are 681,668,678,412,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,668,678,412,557 is 2949133536084.
Find LCM of 681,668,678,412,557 with Prime Factorization
| 2 | 681, 668, 678, 412, 557 |
| 2 | 681, 334, 339, 206, 557 |
| 3 | 681, 167, 339, 103, 557 |
| 227, 167, 113, 103, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 227 x 167 x 113 x 103 x 557 = 2949133536084
Therefore, the lowest common multiple of 681,668,678,412,557 is 2949133536084.
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.
681 x 668 x 678 x 412 x 557 = 70779204866016
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.
681 : 1, 3, 227, 681
668 : 1, 2, 4, 167, 334, 668
678 : 1, 2, 3, 6, 113, 226, 339, 678
412 : 1, 2, 4, 103, 206, 412
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,668,678,412,557, is 1.
Now, the common factors can be found like this.
681:3x 227
668:2x 2x 167
678:2x 3x 113
412:2x 2x 103
557:557
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 70779204866016/(1x24)
LCM = 70779204866016/24
LCM = 2949133536084
Thus, we can understand that the LCM of 681,668,678,412,557 is 2949133536084.
