Find LCM of 449,650,396,782,780 with Prime Factorization
| 2 | 449, 650, 396, 782, 780 |
| 2 | 449, 325, 198, 391, 390 |
| 3 | 449, 325, 99, 391, 195 |
| 5 | 449, 325, 33, 391, 65 |
| 13 | 449, 13, 33, 391, 65 |
| 449, 1, 33, 391, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 449 x 1 x 33 x 391 x 5 = 22594443300
Therefore, the lowest common multiple of 449,650,396,782,780 is 22594443300.
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.
449 x 650 x 396 x 782 x 780 = 70494663096000
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.
449 : 1, 449
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
782 : 1, 2, 17, 23, 34, 46, 391, 782
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 449,650,396,782,780, is 1.
Now, the common factors can be found like this.
449:449
650:2x 5x 5x 13
396:2x 2x 3x 3x 11
782:2x 17x 23
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 2x 2x 3x 5x 13 = 3120
Therefore, the value for common factors is 3120.
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 = 70494663096000/(1x3120)
LCM = 70494663096000/3120
LCM = 22594443300
Thus, we can understand that the LCM of 449,650,396,782,780 is 22594443300.
