The LCM of 867,575,782,342 is 56831850.
Find LCM of 867,575,782,342 with Prime Factorization
| 2 | 867, 575, 782, 342 |
| 3 | 867, 575, 391, 171 |
| 17 | 289, 575, 391, 57 |
| 23 | 17, 575, 23, 57 |
| 17, 25, 1, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 23 x 17 x 25 x 1 x 57 = 56831850
Therefore, the lowest common multiple of 867,575,782,342 is 56831850.
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.
867 x 575 x 782 x 342 = 133327520100
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.
867 : 1, 3, 17, 51, 289, 867
575 : 1, 5, 23, 25, 115, 575
782 : 1, 2, 17, 23, 34, 46, 391, 782
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,575,782,342, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
575:5x 5x 23
782:2x 17x 23
342:2x 3x 3x 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 3x 17x 23 = 2346
Therefore, the value for common factors is 2346.
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 = 133327520100/(1x2346)
LCM = 133327520100/2346
LCM = 56831850
Thus, we can understand that the LCM of 867,575,782,342 is 56831850.
