Given numbers are 828,314,346,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 828,314,346,689 is 15495133212.
Find LCM of 828,314,346,689 with Prime Factorization
| 2 | 828, 314, 346, 689 |
| 414, 157, 173, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 414 x 157 x 173 x 689 = 15495133212
Therefore, the lowest common multiple of 828,314,346,689 is 15495133212.
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.
828 x 314 x 346 x 689 = 61980532848
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
314 : 1, 2, 157, 314
346 : 1, 2, 173, 346
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,314,346,689, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
314:2x 157
346:2x 173
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 61980532848/(1x4)
LCM = 61980532848/4
LCM = 15495133212
Thus, we can understand that the LCM of 828,314,346,689 is 15495133212.
