Given numbers are 343,740,561,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,740,561,812 is 4129397580.
Find LCM of 343,740,561,812 with Prime Factorization
| 2 | 343, 740, 561, 812 |
| 2 | 343, 370, 561, 406 |
| 7 | 343, 185, 561, 203 |
| 49, 185, 561, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 49 x 185 x 561 x 29 = 4129397580
Therefore, the lowest common multiple of 343,740,561,812 is 4129397580.
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.
343 x 740 x 561 x 812 = 115623132240
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.
343 : 1, 7, 49, 343
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
561 : 1, 3, 11, 17, 33, 51, 187, 561
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,740,561,812, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
740:2x 2x 5x 37
561:3x 11x 17
812:2x 2x 7x 29
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 7 = 28
Therefore, the value for common factors is 28.
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 = 115623132240/(1x28)
LCM = 115623132240/28
LCM = 4129397580
Thus, we can understand that the LCM of 343,740,561,812 is 4129397580.
