Given numbers are 631,987,909,913,108
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,987,909,913,108 is 2067479271396.
Find LCM of 631,987,909,913,108 with Prime Factorization
3 | 631, 987, 909, 913, 108 |
3 | 631, 329, 303, 913, 36 |
631, 329, 101, 913, 12 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 631 x 329 x 101 x 913 x 12 = 2067479271396
Therefore, the lowest common multiple of 631,987,909,913,108 is 2067479271396.
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.
631 x 987 x 909 x 913 x 108 = 55821940327692
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.
631 : 1, 631
987 : 1, 3, 7, 21, 47, 141, 329, 987
909 : 1, 3, 9, 101, 303, 909
913 : 1, 11, 83, 913
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,987,909,913,108, is 1.
Now, the common factors can be found like this.
631:631
987:3x 7x 47
909:3x 3x 101
913:11x 83
108:2x 2x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 55821940327692/(1x27)
LCM = 55821940327692/27
LCM = 2067479271396
Thus, we can understand that the LCM of 631,987,909,913,108 is 2067479271396.
