Given numbers are 631,824,139,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,824,139,138 is 4986782904.
Find LCM of 631,824,139,138 with Prime Factorization
2 | 631, 824, 139, 138 |
631, 412, 139, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 631 x 412 x 139 x 69 = 4986782904
Therefore, the lowest common multiple of 631,824,139,138 is 4986782904.
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 824 x 139 x 138 = 9973565808
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
824 : 1, 2, 4, 8, 103, 206, 412, 824
139 : 1, 139
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,824,139,138, is 1.
Now, the common factors can be found like this.
631:631
824:2x 2x 2x 103
139:139
138:2x 3x 23
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 = 9973565808/(1x2)
LCM = 9973565808/2
LCM = 4986782904
Thus, we can understand that the LCM of 631,824,139,138 is 4986782904.
