Find LCM of 618,585,748,256,121 with Prime Factorization
| 2 | 618, 585, 748, 256, 121 |
| 2 | 309, 585, 374, 128, 121 |
| 3 | 309, 585, 187, 64, 121 |
| 11 | 103, 195, 187, 64, 121 |
| 103, 195, 17, 64, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 103 x 195 x 17 x 64 x 11 = 31729800960
Therefore, the lowest common multiple of 618,585,748,256,121 is 31729800960.
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.
618 x 585 x 748 x 256 x 121 = 8376667453440
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,585,748,256,121, is 1.
Now, the common factors can be found like this.
618:2x 3x 103
585:3x 3x 5x 13
748:2x 2x 11x 17
256:2x 2x 2x 2x 2x 2x 2x 2
121:11x 11
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 8376667453440/(1x264)
LCM = 8376667453440/264
LCM = 31729800960
Thus, we can understand that the LCM of 618,585,748,256,121 is 31729800960.
