Given numbers are 281,427,168,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,427,168,493 is 1419686184.
Find LCM of 281,427,168,493 with Prime Factorization
| 7 | 281, 427, 168, 493 |
| 281, 61, 24, 493 |
Multiply the prime numbers at the bottom and the left side.
7 x 281 x 61 x 24 x 493 = 1419686184
Therefore, the lowest common multiple of 281,427,168,493 is 1419686184.
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.
281 x 427 x 168 x 493 = 9937803288
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.
281 : 1, 281
427 : 1, 7, 61, 427
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,427,168,493, is 1.
Now, the common factors can be found like this.
281:281
427:7x 61
168:2x 2x 2x 3x 7
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 9937803288/(1x7)
LCM = 9937803288/7
LCM = 1419686184
Thus, we can understand that the LCM of 281,427,168,493 is 1419686184.
