Given numbers are 691,643,404,404,151
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,643,404,404,151 is 27104870252.
Find LCM of 691,643,404,404,151 with Prime Factorization
2 | 691, 643, 404, 404, 151 |
2 | 691, 643, 202, 202, 151 |
101 | 691, 643, 101, 101, 151 |
691, 643, 1, 1, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 691 x 643 x 1 x 1 x 151 = 27104870252
Therefore, the lowest common multiple of 691,643,404,404,151 is 27104870252.
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.
691 x 643 x 404 x 404 x 151 = 10950367581808
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.
691 : 1, 691
643 : 1, 643
404 : 1, 2, 4, 101, 202, 404
404 : 1, 2, 4, 101, 202, 404
151 : 1, 151
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,643,404,404,151, is 1.
Now, the common factors can be found like this.
691:691
643:643
404:2x 2x 101
404:2x 2x 101
151:151
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 101 = 404
Therefore, the value for common factors is 404.
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 = 10950367581808/(1x404)
LCM = 10950367581808/404
LCM = 27104870252
Thus, we can understand that the LCM of 691,643,404,404,151 is 27104870252.
