Given numbers are 995,938,268,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 995,938,268,398 is 1866620.
Find LCM of 995,938,268,398 with Prime Factorization
| 2 | 995, 938, 268, 398 |
| 67 | 995, 469, 134, 199 |
| 199 | 995, 7, 2, 199 |
| 5, 7, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 67 x 199 x 5 x 7 x 2 x 1 = 1866620
Therefore, the lowest common multiple of 995,938,268,398 is 1866620.
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.
995 x 938 x 268 x 398 = 99550577840
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.
995 : 1, 5, 199, 995
938 : 1, 2, 7, 14, 67, 134, 469, 938
268 : 1, 2, 4, 67, 134, 268
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 995,938,268,398, is 1.
Now, the common factors can be found like this.
995:5x 199
938:2x 7x 67
268:2x 2x 67
398:2x 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 2x 67x 199 = 53332
Therefore, the value for common factors is 53332.
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 = 99550577840/(1x53332)
LCM = 99550577840/53332
LCM = 1866620
Thus, we can understand that the LCM of 995,938,268,398 is 1866620.
