Find LCM of 821,741,344,469,448 with Prime Factorization
| 2 | 821, 741, 344, 469, 448 |
| 2 | 821, 741, 172, 469, 224 |
| 2 | 821, 741, 86, 469, 112 |
| 7 | 821, 741, 43, 469, 56 |
| 821, 741, 43, 67, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 821 x 741 x 43 x 67 x 8 = 785204242368
Therefore, the lowest common multiple of 821,741,344,469,448 is 785204242368.
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.
821 x 741 x 344 x 469 x 448 = 43971437572608
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.
821 : 1, 821
741 : 1, 3, 13, 19, 39, 57, 247, 741
344 : 1, 2, 4, 8, 43, 86, 172, 344
469 : 1, 7, 67, 469
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,741,344,469,448, is 1.
Now, the common factors can be found like this.
821:821
741:3x 13x 19
344:2x 2x 2x 43
469:7x 67
448:2x 2x 2x 2x 2x 2x 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 7 = 56
Therefore, the value for common factors is 56.
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 = 43971437572608/(1x56)
LCM = 43971437572608/56
LCM = 785204242368
Thus, we can understand that the LCM of 821,741,344,469,448 is 785204242368.
