Given numbers are 355,198,414,104,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,198,414,104,639 is 84066840.
Find LCM of 355,198,414,104,639 with Prime Factorization
| 2 | 355, 198, 414, 104, 639 |
| 3 | 355, 99, 207, 52, 639 |
| 3 | 355, 33, 69, 52, 213 |
| 71 | 355, 11, 23, 52, 71 |
| 5, 11, 23, 52, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 71 x 5 x 11 x 23 x 52 x 1 = 84066840
Therefore, the lowest common multiple of 355,198,414,104,639 is 84066840.
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.
355 x 198 x 414 x 104 x 639 = 1933873587360
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.
355 : 1, 5, 71, 355
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
104 : 1, 2, 4, 8, 13, 26, 52, 104
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,198,414,104,639, is 1.
Now, the common factors can be found like this.
355:5x 71
198:2x 3x 3x 11
414:2x 3x 3x 23
104:2x 2x 2x 13
639:3x 3x 71
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 3x 3x 3x 71 = 23004
Therefore, the value for common factors is 23004.
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 = 1933873587360/(1x23004)
LCM = 1933873587360/23004
LCM = 84066840
Thus, we can understand that the LCM of 355,198,414,104,639 is 84066840.
