Given numbers are 635,286,972,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,286,972,991 is 87468097860.
Find LCM of 635,286,972,991 with Prime Factorization
| 2 | 635, 286, 972, 991 |
| 635, 143, 486, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 635 x 143 x 486 x 991 = 87468097860
Therefore, the lowest common multiple of 635,286,972,991 is 87468097860.
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.
635 x 286 x 972 x 991 = 174936195720
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.
635 : 1, 5, 127, 635
286 : 1, 2, 11, 13, 22, 26, 143, 286
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,286,972,991, is 1.
Now, the common factors can be found like this.
635:5x 127
286:2x 11x 13
972:2x 2x 3x 3x 3x 3x 3
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 174936195720/(1x2)
LCM = 174936195720/2
LCM = 87468097860
Thus, we can understand that the LCM of 635,286,972,991 is 87468097860.
