Find LCM of 782,897,663,811,655 with Prime Factorization
| 3 | 782, 897, 663, 811, 655 |
| 13 | 782, 299, 221, 811, 655 |
| 17 | 782, 23, 17, 811, 655 |
| 23 | 46, 23, 1, 811, 655 |
| 2, 1, 1, 811, 655 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 23 x 2 x 1 x 1 x 811 x 655 = 16200690090
Therefore, the lowest common multiple of 782,897,663,811,655 is 16200690090.
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.
782 x 897 x 663 x 811 x 655 = 247044323182410
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
897 : 1, 3, 13, 23, 39, 69, 299, 897
663 : 1, 3, 13, 17, 39, 51, 221, 663
811 : 1, 811
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,897,663,811,655, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
897:3x 13x 23
663:3x 13x 17
811:811
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 17x 23 = 15249
Therefore, the value for common factors is 15249.
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 = 247044323182410/(1x15249)
LCM = 247044323182410/15249
LCM = 16200690090
Thus, we can understand that the LCM of 782,897,663,811,655 is 16200690090.
