Given numbers are 690,579,743,415
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,579,743,415 is 8212460730.
Find LCM of 690,579,743,415 with Prime Factorization
| 3 | 690, 579, 743, 415 |
| 5 | 230, 193, 743, 415 |
| 46, 193, 743, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 46 x 193 x 743 x 83 = 8212460730
Therefore, the lowest common multiple of 690,579,743,415 is 8212460730.
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.
690 x 579 x 743 x 415 = 123186910950
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
579 : 1, 3, 193, 579
743 : 1, 743
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,579,743,415, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
579:3x 193
743:743
415:5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 123186910950/(1x15)
LCM = 123186910950/15
LCM = 8212460730
Thus, we can understand that the LCM of 690,579,743,415 is 8212460730.
