Given numbers are 890,690,621,924,409
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,690,621,924,409 is 34811732340.
Find LCM of 890,690,621,924,409 with Prime Factorization
| 2 | 890, 690, 621, 924, 409 |
| 3 | 445, 345, 621, 462, 409 |
| 5 | 445, 115, 207, 154, 409 |
| 23 | 89, 23, 207, 154, 409 |
| 89, 1, 9, 154, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 89 x 1 x 9 x 154 x 409 = 34811732340
Therefore, the lowest common multiple of 890,690,621,924,409 is 34811732340.
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.
890 x 690 x 621 x 924 x 409 = 144120571887600
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
621 : 1, 3, 9, 23, 27, 69, 207, 621
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
409 : 1, 409
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,690,621,924,409, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
690:2x 3x 5x 23
621:3x 3x 3x 23
924:2x 2x 3x 7x 11
409:409
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 3x 5x 23 = 4140
Therefore, the value for common factors is 4140.
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 = 144120571887600/(1x4140)
LCM = 144120571887600/4140
LCM = 34811732340
Thus, we can understand that the LCM of 890,690,621,924,409 is 34811732340.
