Given numbers are 615,501,103,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,501,103,618 is 21157230.
Find LCM of 615,501,103,618 with Prime Factorization
| 3 | 615, 501, 103, 618 |
| 103 | 205, 167, 103, 206 |
| 205, 167, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 103 x 205 x 167 x 1 x 2 = 21157230
Therefore, the lowest common multiple of 615,501,103,618 is 21157230.
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.
615 x 501 x 103 x 618 = 19612752210
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
501 : 1, 3, 167, 501
103 : 1, 103
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,501,103,618, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
501:3x 167
103:103
618:2x 3x 103
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 103 = 927
Therefore, the value for common factors is 927.
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 = 19612752210/(1x927)
LCM = 19612752210/927
LCM = 21157230
Thus, we can understand that the LCM of 615,501,103,618 is 21157230.
