Given numbers are 890,542,808,404,982
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,542,808,404,982 is 47843413160.
Find LCM of 890,542,808,404,982 with Prime Factorization
| 2 | 890, 542, 808, 404, 982 |
| 2 | 445, 271, 404, 202, 491 |
| 101 | 445, 271, 101, 202, 491 |
| 445, 271, 1, 2, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 445 x 271 x 1 x 2 x 491 = 47843413160
Therefore, the lowest common multiple of 890,542,808,404,982 is 47843413160.
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.
890 x 542 x 808 x 404 x 982 = 154629911333120
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
542 : 1, 2, 271, 542
808 : 1, 2, 4, 8, 101, 202, 404, 808
404 : 1, 2, 4, 101, 202, 404
982 : 1, 2, 491, 982
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,542,808,404,982, is 2.
Now, the common factors can be found like this.
890:2x 5x 89
542:2x 271
808:2x 2x 2x 101
404:2x 2x 101
982:2x 491
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 101 = 1616
Therefore, the value for common factors is 1616.
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 = 154629911333120/(2x1616)
LCM = 154629911333120/3232
LCM = 47843413160
Thus, we can understand that the LCM of 890,542,808,404,982 is 47843413160.
