The LCM of 864,841,206,618 is 74842272.
Find LCM of 864,841,206,618 with Prime Factorization
| 2 | 864, 841, 206, 618 |
| 3 | 432, 841, 103, 309 |
| 103 | 144, 841, 103, 103 |
| 144, 841, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 144 x 841 x 1 x 1 = 74842272
Therefore, the lowest common multiple of 864,841,206,618 is 74842272.
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.
864 x 841 x 206 x 618 = 92505048192
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
841 : 1, 29, 841
206 : 1, 2, 103, 206
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 864,841,206,618, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
841:29x 29
206:2x 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.
2x 2x 3x 103 = 1236
Therefore, the value for common factors is 1236.
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 = 92505048192/(1x1236)
LCM = 92505048192/1236
LCM = 74842272
Thus, we can understand that the LCM of 864,841,206,618 is 74842272.
