Given numbers are 374,403,342,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 374,403,342,247 is 25773462.
Find LCM of 374,403,342,247 with Prime Factorization
| 2 | 374, 403, 342, 247 |
| 13 | 187, 403, 171, 247 |
| 19 | 187, 31, 171, 19 |
| 187, 31, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 187 x 31 x 9 x 1 = 25773462
Therefore, the lowest common multiple of 374,403,342,247 is 25773462.
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.
374 x 403 x 342 x 247 = 12732090228
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.
374 : 1, 2, 11, 17, 22, 34, 187, 374
403 : 1, 13, 31, 403
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 374,403,342,247, is 1.
Now, the common factors can be found like this.
374:2x 11x 17
403:13x 31
342:2x 3x 3x 19
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 19 = 494
Therefore, the value for common factors is 494.
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 = 12732090228/(1x494)
LCM = 12732090228/494
LCM = 25773462
Thus, we can understand that the LCM of 374,403,342,247 is 25773462.
