Find LCM of 437,660,782,798 with Prime Factorization
| 2 | 437, 660, 782, 798 |
| 3 | 437, 330, 391, 399 |
| 19 | 437, 110, 391, 133 |
| 23 | 23, 110, 391, 7 |
| 1, 110, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 23 x 1 x 110 x 17 x 7 = 34321980
Therefore, the lowest common multiple of 437,660,782,798 is 34321980.
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.
437 x 660 x 782 x 798 = 179984463120
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.
437 : 1, 19, 23, 437
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
782 : 1, 2, 17, 23, 34, 46, 391, 782
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,660,782,798, is 1.
Now, the common factors can be found like this.
437:19x 23
660:2x 2x 3x 5x 11
782:2x 17x 23
798:2x 3x 7x 19
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 19x 23 = 5244
Therefore, the value for common factors is 5244.
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 = 179984463120/(1x5244)
LCM = 179984463120/5244
LCM = 34321980
Thus, we can understand that the LCM of 437,660,782,798 is 34321980.
