Find LCM of 874,575,640,800 with Prime Factorization
| 2 | 874, 575, 640, 800 |
| 2 | 437, 575, 320, 400 |
| 2 | 437, 575, 160, 200 |
| 2 | 437, 575, 80, 100 |
| 2 | 437, 575, 40, 50 |
| 5 | 437, 575, 20, 25 |
| 5 | 437, 115, 4, 5 |
| 23 | 437, 23, 4, 1 |
| 19, 1, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 5 x 23 x 19 x 1 x 4 x 1 = 1398400
Therefore, the lowest common multiple of 874,575,640,800 is 1398400.
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.
874 x 575 x 640 x 800 = 257305600000
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
575 : 1, 5, 23, 25, 115, 575
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,575,640,800, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
575:5x 5x 23
640:2x 2x 2x 2x 2x 2x 2x 5
800:2x 2x 2x 2x 2x 5x 5
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 5x 5x 5x 23 = 184000
Therefore, the value for common factors is 184000.
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 = 257305600000/(1x184000)
LCM = 257305600000/184000
LCM = 1398400
Thus, we can understand that the LCM of 874,575,640,800 is 1398400.
