Given numbers are 874,615,417,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,615,417,255 is 1270136130.
Find LCM of 874,615,417,255 with Prime Factorization
| 3 | 874, 615, 417, 255 |
| 5 | 874, 205, 139, 85 |
| 874, 41, 139, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 874 x 41 x 139 x 17 = 1270136130
Therefore, the lowest common multiple of 874,615,417,255 is 1270136130.
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.
874 x 615 x 417 x 255 = 57156125850
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
615 : 1, 3, 5, 15, 41, 123, 205, 615
417 : 1, 3, 139, 417
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,615,417,255, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
615:3x 5x 41
417:3x 139
255:3x 5x 17
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 5 = 45
Therefore, the value for common factors is 45.
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 = 57156125850/(1x45)
LCM = 57156125850/45
LCM = 1270136130
Thus, we can understand that the LCM of 874,615,417,255 is 1270136130.
