Find LCM of 521,172,897,933,780 with Prime Factorization
| 2 | 521, 172, 897, 933, 780 |
| 2 | 521, 86, 897, 933, 390 |
| 3 | 521, 43, 897, 933, 195 |
| 13 | 521, 43, 299, 311, 65 |
| 521, 43, 23, 311, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 521 x 43 x 23 x 311 x 5 = 124993954020
Therefore, the lowest common multiple of 521,172,897,933,780 is 124993954020.
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.
521 x 172 x 897 x 933 x 780 = 58497170481360
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.
521 : 1, 521
172 : 1, 2, 4, 43, 86, 172
897 : 1, 3, 13, 23, 39, 69, 299, 897
933 : 1, 3, 311, 933
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,172,897,933,780, is 1.
Now, the common factors can be found like this.
521:521
172:2x 2x 43
897:3x 13x 23
933:3x 311
780:2x 2x 3x 5x 13
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 13 = 468
Therefore, the value for common factors is 468.
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 = 58497170481360/(1x468)
LCM = 58497170481360/468
LCM = 124993954020
Thus, we can understand that the LCM of 521,172,897,933,780 is 124993954020.
