Given numbers are 678,823,734,138,759
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,823,734,138,759 is 51810300894.
Find LCM of 678,823,734,138,759 with Prime Factorization
| 2 | 678, 823, 734, 138, 759 |
| 3 | 339, 823, 367, 69, 759 |
| 23 | 113, 823, 367, 23, 253 |
| 113, 823, 367, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 113 x 823 x 367 x 1 x 11 = 51810300894
Therefore, the lowest common multiple of 678,823,734,138,759 is 51810300894.
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.
678 x 823 x 734 x 138 x 759 = 42898929140232
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
823 : 1, 823
734 : 1, 2, 367, 734
138 : 1, 2, 3, 6, 23, 46, 69, 138
759 : 1, 3, 11, 23, 33, 69, 253, 759
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,823,734,138,759, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
823:823
734:2x 367
138:2x 3x 23
759:3x 11x 23
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 3x 3x 23 = 828
Therefore, the value for common factors is 828.
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 = 42898929140232/(1x828)
LCM = 42898929140232/828
LCM = 51810300894
Thus, we can understand that the LCM of 678,823,734,138,759 is 51810300894.
