Given numbers are 879,561,295,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 879,561,295,646 is 1842621330.
Find LCM of 879,561,295,646 with Prime Factorization
| 3 | 879, 561, 295, 646 |
| 17 | 293, 187, 295, 646 |
| 293, 11, 295, 38 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 293 x 11 x 295 x 38 = 1842621330
Therefore, the lowest common multiple of 879,561,295,646 is 1842621330.
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.
879 x 561 x 295 x 646 = 93973687830
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.
879 : 1, 3, 293, 879
561 : 1, 3, 11, 17, 33, 51, 187, 561
295 : 1, 5, 59, 295
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 879,561,295,646, is 1.
Now, the common factors can be found like this.
879:3x 293
561:3x 11x 17
295:5x 59
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 93973687830/(1x51)
LCM = 93973687830/51
LCM = 1842621330
Thus, we can understand that the LCM of 879,561,295,646 is 1842621330.
