Given numbers are 657,180,359,741,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,180,359,741,921 is 357705108540.
Find LCM of 657,180,359,741,921 with Prime Factorization
3 | 657, 180, 359, 741, 921 |
3 | 219, 60, 359, 247, 307 |
73, 20, 359, 247, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 73 x 20 x 359 x 247 x 307 = 357705108540
Therefore, the lowest common multiple of 657,180,359,741,921 is 357705108540.
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 180 x 359 x 741 x 921 = 28974113791740
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
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
359 : 1, 359
741 : 1, 3, 13, 19, 39, 57, 247, 741
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,180,359,741,921, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
180:2x 2x 3x 3x 5
359:359
741:3x 13x 19
921:3x 307
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 3 = 81
Therefore, the value for common factors is 81.
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 = 28974113791740/(1x81)
LCM = 28974113791740/81
LCM = 357705108540
Thus, we can understand that the LCM of 657,180,359,741,921 is 357705108540.
