Find LCM of 813,629,120,897,644 with Prime Factorization
2 | 813, 629, 120, 897, 644 |
2 | 813, 629, 60, 897, 322 |
3 | 813, 629, 30, 897, 161 |
23 | 271, 629, 10, 299, 161 |
271, 629, 10, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 271 x 629 x 10 x 13 x 7 = 42812482440
Therefore, the lowest common multiple of 813,629,120,897,644 is 42812482440.
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.
813 x 629 x 120 x 897 x 644 = 35448735460320
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.
813 : 1, 3, 271, 813
629 : 1, 17, 37, 629
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
897 : 1, 3, 13, 23, 39, 69, 299, 897
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,629,120,897,644, is 1.
Now, the common factors can be found like this.
813:3x 271
629:17x 37
120:2x 2x 2x 3x 5
897:3x 13x 23
644:2x 2x 7x 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 23 = 828
Therefore, the value for common factors is 828.
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 = 35448735460320/(1x828)
LCM = 35448735460320/828
LCM = 42812482440
Thus, we can understand that the LCM of 813,629,120,897,644 is 42812482440.
