Given numbers are 199,808,770,404
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 199,808,770,404 is 61904920.
Find LCM of 199,808,770,404 with Prime Factorization
| 2 | 199, 808, 770, 404 |
| 2 | 199, 404, 385, 202 |
| 101 | 199, 101, 385, 202 |
| 199, 1, 385, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 199 x 1 x 385 x 2 = 61904920
Therefore, the lowest common multiple of 199,808,770,404 is 61904920.
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.
199 x 808 x 770 x 404 = 50019175360
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.
199 : 1, 199
808 : 1, 2, 4, 8, 101, 202, 404, 808
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
404 : 1, 2, 4, 101, 202, 404
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 199,808,770,404, is 1.
Now, the common factors can be found like this.
199:199
808:2x 2x 2x 101
770:2x 5x 7x 11
404:2x 2x 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 101 = 808
Therefore, the value for common factors is 808.
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 = 50019175360/(1x808)
LCM = 50019175360/808
LCM = 61904920
Thus, we can understand that the LCM of 199,808,770,404 is 61904920.
