Given numbers are 413,431,862,668,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 413,431,862,668,681 is 80974988724.
Find LCM of 413,431,862,668,681 with Prime Factorization
| 2 | 413, 431, 862, 668, 681 |
| 431 | 413, 431, 431, 334, 681 |
| 413, 1, 1, 334, 681 |
Multiply the prime numbers at the bottom and the left side.
2 x 431 x 413 x 1 x 1 x 334 x 681 = 80974988724
Therefore, the lowest common multiple of 413,431,862,668,681 is 80974988724.
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.
413 x 431 x 862 x 668 x 681 = 69800440280088
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.
413 : 1, 7, 59, 413
431 : 1, 431
862 : 1, 2, 431, 862
668 : 1, 2, 4, 167, 334, 668
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 413,431,862,668,681, is 1.
Now, the common factors can be found like this.
413:7x 59
431:431
862:2x 431
668:2x 2x 167
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 431 = 862
Therefore, the value for common factors is 862.
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 = 69800440280088/(1x862)
LCM = 69800440280088/862
LCM = 80974988724
Thus, we can understand that the LCM of 413,431,862,668,681 is 80974988724.
