Given numbers are 341,247,423,980,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 341,247,423,980,399 is 34915460580.
Find LCM of 341,247,423,980,399 with Prime Factorization
| 3 | 341, 247, 423, 980, 399 |
| 7 | 341, 247, 141, 980, 133 |
| 19 | 341, 247, 141, 140, 19 |
| 341, 13, 141, 140, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 341 x 13 x 141 x 140 x 1 = 34915460580
Therefore, the lowest common multiple of 341,247,423,980,399 is 34915460580.
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.
341 x 247 x 423 x 980 x 399 = 13931268771420
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.
341 : 1, 11, 31, 341
247 : 1, 13, 19, 247
423 : 1, 3, 9, 47, 141, 423
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 341,247,423,980,399, is 1.
Now, the common factors can be found like this.
341:11x 31
247:13x 19
423:3x 3x 47
980:2x 2x 5x 7x 7
399:3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 19 = 399
Therefore, the value for common factors is 399.
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 = 13931268771420/(1x399)
LCM = 13931268771420/399
LCM = 34915460580
Thus, we can understand that the LCM of 341,247,423,980,399 is 34915460580.
