Given numbers are 311,363,975,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,363,975,988 is 2788457100.
Find LCM of 311,363,975,988 with Prime Factorization
3 | 311, 363, 975, 988 |
13 | 311, 121, 325, 988 |
311, 121, 25, 76 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 311 x 121 x 25 x 76 = 2788457100
Therefore, the lowest common multiple of 311,363,975,988 is 2788457100.
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.
311 x 363 x 975 x 988 = 108749826900
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.
311 : 1, 311
363 : 1, 3, 11, 33, 121, 363
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,363,975,988, is 1.
Now, the common factors can be found like this.
311:311
363:3x 11x 11
975:3x 5x 5x 13
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 108749826900/(1x39)
LCM = 108749826900/39
LCM = 2788457100
Thus, we can understand that the LCM of 311,363,975,988 is 2788457100.
