Find LCM of 513,621,644,276 with Prime Factorization
| 2 | 513, 621, 644, 276 |
| 2 | 513, 621, 322, 138 |
| 3 | 513, 621, 161, 69 |
| 3 | 171, 207, 161, 23 |
| 3 | 57, 69, 161, 23 |
| 23 | 19, 23, 161, 23 |
| 19, 1, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 23 x 19 x 1 x 7 x 1 = 330372
Therefore, the lowest common multiple of 513,621,644,276 is 330372.
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.
513 x 621 x 644 x 276 = 56624439312
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
621 : 1, 3, 9, 23, 27, 69, 207, 621
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,621,644,276, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
621:3x 3x 3x 23
644:2x 2x 7x 23
276:2x 2x 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 2x 3x 3x 3x 3x 23x 23 = 171396
Therefore, the value for common factors is 171396.
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 = 56624439312/(1x171396)
LCM = 56624439312/171396
LCM = 330372
Thus, we can understand that the LCM of 513,621,644,276 is 330372.
