Given numbers are 361,756,362,171,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,756,362,171,423 is 2321696412.
Find LCM of 361,756,362,171,423 with Prime Factorization
| 2 | 361, 756, 362, 171, 423 |
| 3 | 361, 378, 181, 171, 423 |
| 3 | 361, 126, 181, 57, 141 |
| 19 | 361, 42, 181, 19, 47 |
| 1, 42, 181, 19, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 1 x 42 x 181 x 19 x 47 = 2321696412
Therefore, the lowest common multiple of 361,756,362,171,423 is 2321696412.
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 756 x 362 x 171 x 423 = 7146181556136
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
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
362 : 1, 2, 181, 362
171 : 1, 3, 9, 19, 57, 171
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,756,362,171,423, is 1.
Now, the common factors can be found like this.
361:19x 19
756:2x 2x 3x 3x 3x 7
362:2x 181
171:3x 3x 19
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 19 = 3078
Therefore, the value for common factors is 3078.
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 = 7146181556136/(1x3078)
LCM = 7146181556136/3078
LCM = 2321696412
Thus, we can understand that the LCM of 361,756,362,171,423 is 2321696412.
