Find LCM of 749,800,780,544,842 with Prime Factorization
| 2 | 749, 800, 780, 544, 842 |
| 2 | 749, 400, 390, 272, 421 |
| 2 | 749, 200, 195, 136, 421 |
| 2 | 749, 100, 195, 68, 421 |
| 2 | 749, 50, 195, 34, 421 |
| 5 | 749, 25, 195, 17, 421 |
| 749, 5, 39, 17, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 749 x 5 x 39 x 17 x 421 = 167250501600
Therefore, the lowest common multiple of 749,800,780,544,842 is 167250501600.
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.
749 x 800 x 780 x 544 x 842 = 214080642048000
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.
749 : 1, 7, 107, 749
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
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
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,800,780,544,842, is 1.
Now, the common factors can be found like this.
749:7x 107
800:2x 2x 2x 2x 2x 5x 5
780:2x 2x 3x 5x 13
544:2x 2x 2x 2x 2x 17
842:2x 421
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 2x 2x 2x 2x 5 = 1280
Therefore, the value for common factors is 1280.
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 = 214080642048000/(1x1280)
LCM = 214080642048000/1280
LCM = 167250501600
Thus, we can understand that the LCM of 749,800,780,544,842 is 167250501600.
