Given numbers are 400,897,273,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,897,273,971 is 2438763600.
Find LCM of 400,897,273,971 with Prime Factorization
| 3 | 400, 897, 273, 971 |
| 13 | 400, 299, 91, 971 |
| 400, 23, 7, 971 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 400 x 23 x 7 x 971 = 2438763600
Therefore, the lowest common multiple of 400,897,273,971 is 2438763600.
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.
400 x 897 x 273 x 971 = 95111780400
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
897 : 1, 3, 13, 23, 39, 69, 299, 897
273 : 1, 3, 7, 13, 21, 39, 91, 273
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,897,273,971, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
897:3x 13x 23
273:3x 7x 13
971:971
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 95111780400/(1x39)
LCM = 95111780400/39
LCM = 2438763600
Thus, we can understand that the LCM of 400,897,273,971 is 2438763600.
