Find LCM of 495,805,441,421 with Prime Factorization
| 3 | 495, 805, 441, 421 |
| 3 | 165, 805, 147, 421 |
| 5 | 55, 805, 49, 421 |
| 7 | 11, 161, 49, 421 |
| 11, 23, 7, 421 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 11 x 23 x 7 x 421 = 234861165
Therefore, the lowest common multiple of 495,805,441,421 is 234861165.
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.
495 x 805 x 441 x 421 = 73981266975
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
805 : 1, 5, 7, 23, 35, 115, 161, 805
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,805,441,421, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
805:5x 7x 23
441:3x 3x 7x 7
421:421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 73981266975/(1x315)
LCM = 73981266975/315
LCM = 234861165
Thus, we can understand that the LCM of 495,805,441,421 is 234861165.
