Given numbers are 851,744,447,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,744,447,897 is 1226399928.
Find LCM of 851,744,447,897 with Prime Factorization
| 3 | 851, 744, 447, 897 |
| 23 | 851, 248, 149, 299 |
| 37, 248, 149, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 37 x 248 x 149 x 13 = 1226399928
Therefore, the lowest common multiple of 851,744,447,897 is 1226399928.
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.
851 x 744 x 447 x 897 = 253864785096
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.
851 : 1, 23, 37, 851
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
447 : 1, 3, 149, 447
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,744,447,897, is 1.
Now, the common factors can be found like this.
851:23x 37
744:2x 2x 2x 3x 31
447:3x 149
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 253864785096/(1x207)
LCM = 253864785096/207
LCM = 1226399928
Thus, we can understand that the LCM of 851,744,447,897 is 1226399928.
