Given numbers are 8,398,665,190
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8,398,665,190 is 1058680.
Find LCM of 8,398,665,190 with Prime Factorization
| 2 | 8, 398, 665, 190 |
| 5 | 4, 199, 665, 95 |
| 19 | 4, 199, 133, 19 |
| 4, 199, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 4 x 199 x 7 x 1 = 1058680
Therefore, the lowest common multiple of 8,398,665,190 is 1058680.
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.
8 x 398 x 665 x 190 = 402298400
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.
8 : 1, 2, 4, 8
398 : 1, 2, 199, 398
665 : 1, 5, 7, 19, 35, 95, 133, 665
190 : 1, 2, 5, 10, 19, 38, 95, 190
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8,398,665,190, is 1.
Now, the common factors can be found like this.
8:2x 2x 2
398:2x 199
665:5x 7x 19
190:2x 5x 19
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 5x 19 = 380
Therefore, the value for common factors is 380.
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 = 402298400/(1x380)
LCM = 402298400/380
LCM = 1058680
Thus, we can understand that the LCM of 8,398,665,190 is 1058680.
