Find LCM of 235,507,168,656,820 with Prime Factorization
| 2 | 235, 507, 168, 656, 820 |
| 2 | 235, 507, 84, 328, 410 |
| 2 | 235, 507, 42, 164, 205 |
| 3 | 235, 507, 21, 82, 205 |
| 5 | 235, 169, 7, 82, 205 |
| 41 | 47, 169, 7, 82, 41 |
| 47, 169, 7, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 41 x 47 x 169 x 7 x 2 x 1 = 547113840
Therefore, the lowest common multiple of 235,507,168,656,820 is 547113840.
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.
235 x 507 x 168 x 656 x 820 = 10767200371200
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.
235 : 1, 5, 47, 235
507 : 1, 3, 13, 39, 169, 507
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 235,507,168,656,820, is 1.
Now, the common factors can be found like this.
235:5x 47
507:3x 13x 13
168:2x 2x 2x 3x 7
656:2x 2x 2x 2x 41
820:2x 2x 5x 41
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 2x 3x 5x 41 = 19680
Therefore, the value for common factors is 19680.
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 = 10767200371200/(1x19680)
LCM = 10767200371200/19680
LCM = 547113840
Thus, we can understand that the LCM of 235,507,168,656,820 is 547113840.
