Given numbers are 100,105,257,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 100,105,257,618 is 55589100.
Find LCM of 100,105,257,618 with Prime Factorization
| 2 | 100, 105, 257, 618 |
| 3 | 50, 105, 257, 309 |
| 5 | 50, 35, 257, 103 |
| 10, 7, 257, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 10 x 7 x 257 x 103 = 55589100
Therefore, the lowest common multiple of 100,105,257,618 is 55589100.
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.
100 x 105 x 257 x 618 = 1667673000
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
105 : 1, 3, 5, 7, 15, 21, 35, 105
257 : 1, 257
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 100,105,257,618, is 1.
Now, the common factors can be found like this.
100:2x 2x 5x 5
105:3x 5x 7
257:257
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.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 1667673000/(1x30)
LCM = 1667673000/30
LCM = 55589100
Thus, we can understand that the LCM of 100,105,257,618 is 55589100.
