Given numbers are 521,561,648,473,201
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,561,648,473,201 is 181885297176.
Find LCM of 521,561,648,473,201 with Prime Factorization
| 3 | 521, 561, 648, 473, 201 |
| 11 | 521, 187, 216, 473, 67 |
| 521, 17, 216, 43, 67 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 521 x 17 x 216 x 43 x 67 = 181885297176
Therefore, the lowest common multiple of 521,561,648,473,201 is 181885297176.
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.
521 x 561 x 648 x 473 x 201 = 18006644420424
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.
521 : 1, 521
561 : 1, 3, 11, 17, 33, 51, 187, 561
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
473 : 1, 11, 43, 473
201 : 1, 3, 67, 201
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,561,648,473,201, is 1.
Now, the common factors can be found like this.
521:521
561:3x 11x 17
648:2x 2x 2x 3x 3x 3x 3
473:11x 43
201:3x 67
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 11 = 99
Therefore, the value for common factors is 99.
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 = 18006644420424/(1x99)
LCM = 18006644420424/99
LCM = 181885297176
Thus, we can understand that the LCM of 521,561,648,473,201 is 181885297176.
