Given numbers are 287,438,838,741,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,438,838,741,492 is 26019382116.
Find LCM of 287,438,838,741,492 with Prime Factorization
| 2 | 287, 438, 838, 741, 492 |
| 3 | 287, 219, 419, 741, 246 |
| 41 | 287, 73, 419, 247, 82 |
| 7, 73, 419, 247, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 7 x 73 x 419 x 247 x 2 = 26019382116
Therefore, the lowest common multiple of 287,438,838,741,492 is 26019382116.
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.
287 x 438 x 838 x 741 x 492 = 38404608003216
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.
287 : 1, 7, 41, 287
438 : 1, 2, 3, 6, 73, 146, 219, 438
838 : 1, 2, 419, 838
741 : 1, 3, 13, 19, 39, 57, 247, 741
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,438,838,741,492, is 1.
Now, the common factors can be found like this.
287:7x 41
438:2x 3x 73
838:2x 419
741:3x 13x 19
492:2x 2x 3x 41
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 41 = 1476
Therefore, the value for common factors is 1476.
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 = 38404608003216/(1x1476)
LCM = 38404608003216/1476
LCM = 26019382116
Thus, we can understand that the LCM of 287,438,838,741,492 is 26019382116.
