Given numbers are 288,409,393,391,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 288,409,393,391,346 is 1043782357536.
Find LCM of 288,409,393,391,346 with Prime Factorization
| 2 | 288, 409, 393, 391, 346 |
| 3 | 144, 409, 393, 391, 173 |
| 48, 409, 131, 391, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 48 x 409 x 131 x 391 x 173 = 1043782357536
Therefore, the lowest common multiple of 288,409,393,391,346 is 1043782357536.
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.
288 x 409 x 393 x 391 x 346 = 6262694145216
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.
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
409 : 1, 409
393 : 1, 3, 131, 393
391 : 1, 17, 23, 391
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,409,393,391,346, is 1.
Now, the common factors can be found like this.
288:2x 2x 2x 2x 2x 3x 3
409:409
393:3x 131
391:17x 23
346:2x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 6262694145216/(1x6)
LCM = 6262694145216/6
LCM = 1043782357536
Thus, we can understand that the LCM of 288,409,393,391,346 is 1043782357536.
