Given numbers are 657,345,703,529
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,345,703,529 is 1221648795.
Find LCM of 657,345,703,529 with Prime Factorization
| 3 | 657, 345, 703, 529 |
| 23 | 219, 115, 703, 529 |
| 219, 5, 703, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 219 x 5 x 703 x 23 = 1221648795
Therefore, the lowest common multiple of 657,345,703,529 is 1221648795.
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.
657 x 345 x 703 x 529 = 84293766855
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.
657 : 1, 3, 9, 73, 219, 657
345 : 1, 3, 5, 15, 23, 69, 115, 345
703 : 1, 19, 37, 703
529 : 1, 23, 529
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,345,703,529, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
345:3x 5x 23
703:19x 37
529:23x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23 = 69
Therefore, the value for common factors is 69.
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 = 84293766855/(1x69)
LCM = 84293766855/69
LCM = 1221648795
Thus, we can understand that the LCM of 657,345,703,529 is 1221648795.
