Given numbers are 561,286,296,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,286,296,556 is 300063192.
Find LCM of 561,286,296,556 with Prime Factorization
2 | 561, 286, 296, 556 |
2 | 561, 143, 148, 278 |
11 | 561, 143, 74, 139 |
51, 13, 74, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 51 x 13 x 74 x 139 = 300063192
Therefore, the lowest common multiple of 561,286,296,556 is 300063192.
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 286 x 296 x 556 = 26405560896
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
296 : 1, 2, 4, 8, 37, 74, 148, 296
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,286,296,556, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
286:2x 11x 13
296:2x 2x 2x 37
556:2x 2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11 = 88
Therefore, the value for common factors is 88.
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 = 26405560896/(1x88)
LCM = 26405560896/88
LCM = 300063192
Thus, we can understand that the LCM of 561,286,296,556 is 300063192.
