Given numbers are 140,411,612,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,411,612,170 is 2934540.
Find LCM of 140,411,612,170 with Prime Factorization
| 2 | 140, 411, 612, 170 |
| 2 | 70, 411, 306, 85 |
| 3 | 35, 411, 153, 85 |
| 5 | 35, 137, 51, 85 |
| 17 | 7, 137, 51, 17 |
| 7, 137, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 7 x 137 x 3 x 1 = 2934540
Therefore, the lowest common multiple of 140,411,612,170 is 2934540.
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.
140 x 411 x 612 x 170 = 5986461600
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
411 : 1, 3, 137, 411
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,411,612,170, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
411:3x 137
612:2x 2x 3x 3x 17
170:2x 5x 17
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 2x 3x 5x 17 = 2040
Therefore, the value for common factors is 2040.
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 = 5986461600/(1x2040)
LCM = 5986461600/2040
LCM = 2934540
Thus, we can understand that the LCM of 140,411,612,170 is 2934540.
