Given numbers are 668,738,139,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,738,139,894 is 5105095812.
Find LCM of 668,738,139,894 with Prime Factorization
2 | 668, 738, 139, 894 |
3 | 334, 369, 139, 447 |
334, 123, 139, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 334 x 123 x 139 x 149 = 5105095812
Therefore, the lowest common multiple of 668,738,139,894 is 5105095812.
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.
668 x 738 x 139 x 894 = 61261149744
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.
668 : 1, 2, 4, 167, 334, 668
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
139 : 1, 139
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,738,139,894, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
738:2x 3x 3x 41
139:139
894:2x 3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 61261149744/(1x12)
LCM = 61261149744/12
LCM = 5105095812
Thus, we can understand that the LCM of 668,738,139,894 is 5105095812.
