Find LCM of 612,403,918,621 with Prime Factorization
| 2 | 612, 403, 918, 621 |
| 3 | 306, 403, 459, 621 |
| 3 | 102, 403, 153, 207 |
| 3 | 34, 403, 51, 69 |
| 17 | 34, 403, 17, 23 |
| 2, 403, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 17 x 2 x 403 x 1 x 23 = 17017884
Therefore, the lowest common multiple of 612,403,918,621 is 17017884.
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.
612 x 403 x 918 x 621 = 140601757608
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
403 : 1, 13, 31, 403
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,403,918,621, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
403:13x 31
918:2x 3x 3x 3x 17
621:3x 3x 3x 23
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 3x 3x 3x 3x 17 = 8262
Therefore, the value for common factors is 8262.
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 = 140601757608/(1x8262)
LCM = 140601757608/8262
LCM = 17017884
Thus, we can understand that the LCM of 612,403,918,621 is 17017884.
