Given numbers are 670,240,505,571,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,240,505,571,561 is 173414390160.
Find LCM of 670,240,505,571,561 with Prime Factorization
| 2 | 670, 240, 505, 571, 561 |
| 3 | 335, 120, 505, 571, 561 |
| 5 | 335, 40, 505, 571, 187 |
| 67, 8, 101, 571, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 67 x 8 x 101 x 571 x 187 = 173414390160
Therefore, the lowest common multiple of 670,240,505,571,561 is 173414390160.
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.
670 x 240 x 505 x 571 x 561 = 26012158524000
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
505 : 1, 5, 101, 505
571 : 1, 571
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,240,505,571,561, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
240:2x 2x 2x 2x 3x 5
505:5x 101
571:571
561:3x 11x 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 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 26012158524000/(1x150)
LCM = 26012158524000/150
LCM = 173414390160
Thus, we can understand that the LCM of 670,240,505,571,561 is 173414390160.
