Find LCM of 561,168,598,782,686 with Prime Factorization
| 2 | 561, 168, 598, 782, 686 |
| 3 | 561, 84, 299, 391, 343 |
| 7 | 187, 28, 299, 391, 343 |
| 17 | 187, 4, 299, 391, 49 |
| 23 | 11, 4, 299, 23, 49 |
| 11, 4, 13, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 23 x 11 x 4 x 13 x 1 x 49 = 460275816
Therefore, the lowest common multiple of 561,168,598,782,686 is 460275816.
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.
561 x 168 x 598 x 782 x 686 = 30234597801408
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
598 : 1, 2, 13, 23, 26, 46, 299, 598
782 : 1, 2, 17, 23, 34, 46, 391, 782
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,168,598,782,686, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
168:2x 2x 2x 3x 7
598:2x 13x 23
782:2x 17x 23
686:2x 7x 7x 7
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 7x 17x 23 = 65688
Therefore, the value for common factors is 65688.
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 = 30234597801408/(1x65688)
LCM = 30234597801408/65688
LCM = 460275816
Thus, we can understand that the LCM of 561,168,598,782,686 is 460275816.
