Given numbers are 404,338,989,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 404,338,989,661 is 44634001204.
Find LCM of 404,338,989,661 with Prime Factorization
2 | 404, 338, 989, 661 |
202, 169, 989, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 202 x 169 x 989 x 661 = 44634001204
Therefore, the lowest common multiple of 404,338,989,661 is 44634001204.
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.
404 x 338 x 989 x 661 = 89268002408
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.
404 : 1, 2, 4, 101, 202, 404
338 : 1, 2, 13, 26, 169, 338
989 : 1, 23, 43, 989
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 404,338,989,661, is 1.
Now, the common factors can be found like this.
404:2x 2x 101
338:2x 13x 13
989:23x 43
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 89268002408/(1x2)
LCM = 89268002408/2
LCM = 44634001204
Thus, we can understand that the LCM of 404,338,989,661 is 44634001204.
