Given numbers are 312,627,930,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,627,930,561 is 171823080.
Find LCM of 312,627,930,561 with Prime Factorization
2 | 312, 627, 930, 561 |
3 | 156, 627, 465, 561 |
11 | 52, 209, 155, 187 |
52, 19, 155, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 52 x 19 x 155 x 17 = 171823080
Therefore, the lowest common multiple of 312,627,930,561 is 171823080.
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.
312 x 627 x 930 x 561 = 102062909520
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
627 : 1, 3, 11, 19, 33, 57, 209, 627
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
561 : 1, 3, 11, 17, 33, 51, 187, 561
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,627,930,561, is 3.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
627:3x 11x 19
930:2x 3x 5x 31
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 102062909520/(3x198)
LCM = 102062909520/594
LCM = 171823080
Thus, we can understand that the LCM of 312,627,930,561 is 171823080.
