Given numbers are 338,390,681,104,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,390,681,104,661 is 3042953160.
Find LCM of 338,390,681,104,661 with Prime Factorization
| 2 | 338, 390, 681, 104, 661 |
| 3 | 169, 195, 681, 52, 661 |
| 13 | 169, 65, 227, 52, 661 |
| 13, 5, 227, 4, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 13 x 5 x 227 x 4 x 661 = 3042953160
Therefore, the lowest common multiple of 338,390,681,104,661 is 3042953160.
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.
338 x 390 x 681 x 104 x 661 = 6171109008480
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.
338 : 1, 2, 13, 26, 169, 338
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
681 : 1, 3, 227, 681
104 : 1, 2, 4, 8, 13, 26, 52, 104
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,390,681,104,661, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
390:2x 3x 5x 13
681:3x 227
104:2x 2x 2x 13
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.
2x 2x 3x 13x 13 = 2028
Therefore, the value for common factors is 2028.
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 = 6171109008480/(1x2028)
LCM = 6171109008480/2028
LCM = 3042953160
Thus, we can understand that the LCM of 338,390,681,104,661 is 3042953160.
