Given numbers are 657,403,855,657,743
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,403,855,657,743 is 18688861035.
Find LCM of 657,403,855,657,743 with Prime Factorization
| 3 | 657, 403, 855, 657, 743 |
| 3 | 219, 403, 285, 219, 743 |
| 73 | 73, 403, 95, 73, 743 |
| 1, 403, 95, 1, 743 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 73 x 1 x 403 x 95 x 1 x 743 = 18688861035
Therefore, the lowest common multiple of 657,403,855,657,743 is 18688861035.
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 403 x 855 x 657 x 743 = 110507235299955
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
403 : 1, 13, 31, 403
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
657 : 1, 3, 9, 73, 219, 657
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,403,855,657,743, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
403:13x 31
855:3x 3x 5x 19
657:3x 3x 73
743:743
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 73 = 5913
Therefore, the value for common factors is 5913.
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 = 110507235299955/(1x5913)
LCM = 110507235299955/5913
LCM = 18688861035
Thus, we can understand that the LCM of 657,403,855,657,743 is 18688861035.
