Given numbers are 240,436,128,252
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 240,436,128,252 is 4394880.
Find LCM of 240,436,128,252 with Prime Factorization
| 2 | 240, 436, 128, 252 |
| 2 | 120, 218, 64, 126 |
| 2 | 60, 109, 32, 63 |
| 2 | 30, 109, 16, 63 |
| 3 | 15, 109, 8, 63 |
| 5, 109, 8, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 109 x 8 x 21 = 4394880
Therefore, the lowest common multiple of 240,436,128,252 is 4394880.
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.
240 x 436 x 128 x 252 = 3375267840
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
436 : 1, 2, 4, 109, 218, 436
128 : 1, 2, 4, 8, 16, 32, 64, 128
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,436,128,252, is 4.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
436:2x 2x 109
128:2x 2x 2x 2x 2x 2x 2
252:2x 2x 3x 3x 7
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 2x 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 3375267840/(4x192)
LCM = 3375267840/768
LCM = 4394880
Thus, we can understand that the LCM of 240,436,128,252 is 4394880.
