Given numbers are 168,458,224,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 168,458,224,505 is 77713440.
Find LCM of 168,458,224,505 with Prime Factorization
| 2 | 168, 458, 224, 505 |
| 2 | 84, 229, 112, 505 |
| 2 | 42, 229, 56, 505 |
| 7 | 21, 229, 28, 505 |
| 3, 229, 4, 505 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 3 x 229 x 4 x 505 = 77713440
Therefore, the lowest common multiple of 168,458,224,505 is 77713440.
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.
168 x 458 x 224 x 505 = 8703905280
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
458 : 1, 2, 229, 458
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,458,224,505, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
458:2x 229
224:2x 2x 2x 2x 2x 7
505:5x 101
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 7 = 112
Therefore, the value for common factors is 112.
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 = 8703905280/(1x112)
LCM = 8703905280/112
LCM = 77713440
Thus, we can understand that the LCM of 168,458,224,505 is 77713440.
