Given numbers are 561,815,901,212
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,815,901,212 is 96929580.
Find LCM of 561,815,901,212 with Prime Factorization
| 17 | 561, 815, 901, 212 |
| 53 | 33, 815, 53, 212 |
| 33, 815, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
17 x 53 x 33 x 815 x 1 x 4 = 96929580
Therefore, the lowest common multiple of 561,815,901,212 is 96929580.
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.
561 x 815 x 901 x 212 = 87333551580
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
815 : 1, 5, 163, 815
901 : 1, 17, 53, 901
212 : 1, 2, 4, 53, 106, 212
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,815,901,212, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
815:5x 163
901:17x 53
212:2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 53 = 901
Therefore, the value for common factors is 901.
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 = 87333551580/(1x901)
LCM = 87333551580/901
LCM = 96929580
Thus, we can understand that the LCM of 561,815,901,212 is 96929580.
