Given numbers are 311,651,668,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 311,651,668,240 is 2704878960.
Find LCM of 311,651,668,240 with Prime Factorization
2 | 311, 651, 668, 240 |
2 | 311, 651, 334, 120 |
3 | 311, 651, 167, 60 |
311, 217, 167, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 311 x 217 x 167 x 20 = 2704878960
Therefore, the lowest common multiple of 311,651,668,240 is 2704878960.
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.
311 x 651 x 668 x 240 = 32458547520
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.
311 : 1, 311
651 : 1, 3, 7, 21, 31, 93, 217, 651
668 : 1, 2, 4, 167, 334, 668
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,651,668,240, is 1.
Now, the common factors can be found like this.
311:311
651:3x 7x 31
668:2x 2x 167
240:2x 2x 2x 2x 3x 5
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 = 32458547520/(1x12)
LCM = 32458547520/12
LCM = 2704878960
Thus, we can understand that the LCM of 311,651,668,240 is 2704878960.
