Given numbers are 398,785,796
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,785,796 is 624860.
Find LCM of 398,785,796 with Prime Factorization
| 2 | 398, 785, 796 |
| 199 | 199, 785, 398 |
| 1, 785, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 1 x 785 x 2 = 624860
Therefore, the lowest common multiple of 398,785,796 is 624860.
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.
398 x 785 x 796 = 248694280
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.
398 : 1, 2, 199, 398
785 : 1, 5, 157, 785
796 : 1, 2, 4, 199, 398, 796
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,785,796, is 1.
Now, the common factors can be found like this.
398:2x 199
785:5x 157
796:2x 2x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 199 = 398
Therefore, the value for common factors is 398.
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 = 248694280/(1x398)
LCM = 248694280/398
LCM = 624860
Thus, we can understand that the LCM of 398,785,796 is 624860.
