Given numbers are 409,702,754,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,702,754,240 is 333056880.
Find LCM of 409,702,754,240 with Prime Factorization
2 | 409, 702, 754, 240 |
3 | 409, 351, 377, 120 |
13 | 409, 117, 377, 40 |
409, 9, 29, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 409 x 9 x 29 x 40 = 333056880
Therefore, the lowest common multiple of 409,702,754,240 is 333056880.
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.
409 x 702 x 754 x 240 = 51956873280
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.
409 : 1, 409
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
754 : 1, 2, 13, 26, 29, 58, 377, 754
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 409,702,754,240, is 1.
Now, the common factors can be found like this.
409:409
702:2x 3x 3x 3x 13
754:2x 13x 29
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 51956873280/(1x156)
LCM = 51956873280/156
LCM = 333056880
Thus, we can understand that the LCM of 409,702,754,240 is 333056880.
