Find LCM of 755,780,855,872,898 with Prime Factorization
2 | 755, 780, 855, 872, 898 |
2 | 755, 390, 855, 436, 449 |
3 | 755, 195, 855, 218, 449 |
5 | 755, 65, 285, 218, 449 |
151, 13, 57, 218, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 151 x 13 x 57 x 218 x 449 = 657126891720
Therefore, the lowest common multiple of 755,780,855,872,898 is 657126891720.
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.
755 x 780 x 855 x 872 x 898 = 394276135032000
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.
755 : 1, 5, 151, 755
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
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
872 : 1, 2, 4, 8, 109, 218, 436, 872
898 : 1, 2, 449, 898
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,780,855,872,898, is 1.
Now, the common factors can be found like this.
755:5x 151
780:2x 2x 3x 5x 13
855:3x 3x 5x 19
872:2x 2x 2x 109
898:2x 449
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 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 394276135032000/(1x600)
LCM = 394276135032000/600
LCM = 657126891720
Thus, we can understand that the LCM of 755,780,855,872,898 is 657126891720.
