Given numbers are 828,138,707,841
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 828,138,707,841 is 492318036.
Find LCM of 828,138,707,841 with Prime Factorization
| 2 | 828, 138, 707, 841 |
| 3 | 414, 69, 707, 841 |
| 23 | 138, 23, 707, 841 |
| 6, 1, 707, 841 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 6 x 1 x 707 x 841 = 492318036
Therefore, the lowest common multiple of 828,138,707,841 is 492318036.
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 138 x 707 x 841 = 67939888968
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
138 : 1, 2, 3, 6, 23, 46, 69, 138
707 : 1, 7, 101, 707
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,138,707,841, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
138:2x 3x 23
707:7x 101
841:29x 29
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 23 = 138
Therefore, the value for common factors is 138.
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 = 67939888968/(1x138)
LCM = 67939888968/138
LCM = 492318036
Thus, we can understand that the LCM of 828,138,707,841 is 492318036.
