Given numbers are 991,923,403,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,923,403,279 is 255199347.
Find LCM of 991,923,403,279 with Prime Factorization
13 | 991, 923, 403, 279 |
31 | 991, 71, 31, 279 |
991, 71, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
13 x 31 x 991 x 71 x 1 x 9 = 255199347
Therefore, the lowest common multiple of 991,923,403,279 is 255199347.
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.
991 x 923 x 403 x 279 = 102845336841
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.
991 : 1, 991
923 : 1, 13, 71, 923
403 : 1, 13, 31, 403
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,923,403,279, is 1.
Now, the common factors can be found like this.
991:991
923:13x 71
403:13x 31
279:3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 31 = 403
Therefore, the value for common factors is 403.
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 = 102845336841/(1x403)
LCM = 102845336841/403
LCM = 255199347
Thus, we can understand that the LCM of 991,923,403,279 is 255199347.
