Given numbers are 160,216,390,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 160,216,390,618 is 5784480.
Find LCM of 160,216,390,618 with Prime Factorization
| 2 | 160, 216, 390, 618 |
| 2 | 80, 108, 195, 309 |
| 2 | 40, 54, 195, 309 |
| 3 | 20, 27, 195, 309 |
| 5 | 20, 9, 65, 103 |
| 4, 9, 13, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 4 x 9 x 13 x 103 = 5784480
Therefore, the lowest common multiple of 160,216,390,618 is 5784480.
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.
160 x 216 x 390 x 618 = 8329651200
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.
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
618 : 1, 2, 3, 6, 103, 206, 309, 618
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 160,216,390,618, is 2.
Now, the common factors can be found like this.
160:2x 2x 2x 2x 2x 5
216:2x 2x 2x 3x 3x 3
390:2x 3x 5x 13
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 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 8329651200/(2x720)
LCM = 8329651200/1440
LCM = 5784480
Thus, we can understand that the LCM of 160,216,390,618 is 5784480.
