Given numbers are 570,309,398,221,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,309,398,221,618 is 2582007090.
Find LCM of 570,309,398,221,618 with Prime Factorization
| 2 | 570, 309, 398, 221, 618 |
| 3 | 285, 309, 199, 221, 309 |
| 103 | 95, 103, 199, 221, 103 |
| 95, 1, 199, 221, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 95 x 1 x 199 x 221 x 1 = 2582007090
Therefore, the lowest common multiple of 570,309,398,221,618 is 2582007090.
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.
570 x 309 x 398 x 221 x 618 = 9574082289720
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
309 : 1, 3, 103, 309
398 : 1, 2, 199, 398
221 : 1, 13, 17, 221
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 570,309,398,221,618, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
309:3x 103
398:2x 199
221:13x 17
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 2x 3x 3x 103 = 3708
Therefore, the value for common factors is 3708.
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 = 9574082289720/(1x3708)
LCM = 9574082289720/3708
LCM = 2582007090
Thus, we can understand that the LCM of 570,309,398,221,618 is 2582007090.
