Given numbers are 361,366,456,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,366,456,354 is 31181736.
Find LCM of 361,366,456,354 with Prime Factorization
| 2 | 361, 366, 456, 354 |
| 3 | 361, 183, 228, 177 |
| 19 | 361, 61, 76, 59 |
| 19, 61, 4, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 19 x 61 x 4 x 59 = 31181736
Therefore, the lowest common multiple of 361,366,456,354 is 31181736.
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.
361 x 366 x 456 x 354 = 21328307424
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.
361 : 1, 19, 361
366 : 1, 2, 3, 6, 61, 122, 183, 366
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,366,456,354, is 1.
Now, the common factors can be found like this.
361:19x 19
366:2x 3x 61
456:2x 2x 2x 3x 19
354:2x 3x 59
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 19 = 684
Therefore, the value for common factors is 684.
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 = 21328307424/(1x684)
LCM = 21328307424/684
LCM = 31181736
Thus, we can understand that the LCM of 361,366,456,354 is 31181736.
