Given numbers are 808,742,978,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,742,978,899 is 131781310248.
Find LCM of 808,742,978,899 with Prime Factorization
| 2 | 808, 742, 978, 899 |
| 404, 371, 489, 899 |
Multiply the prime numbers at the bottom and the left side.
2 x 404 x 371 x 489 x 899 = 131781310248
Therefore, the lowest common multiple of 808,742,978,899 is 131781310248.
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.
808 x 742 x 978 x 899 = 527125240992
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
742 : 1, 2, 7, 14, 53, 106, 371, 742
978 : 1, 2, 3, 6, 163, 326, 489, 978
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,742,978,899, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
742:2x 7x 53
978:2x 3x 163
899:29x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 527125240992/(1x4)
LCM = 527125240992/4
LCM = 131781310248
Thus, we can understand that the LCM of 808,742,978,899 is 131781310248.
