Given numbers are 709,488,561,709
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 709,488,561,709 is 194101512.
Find LCM of 709,488,561,709 with Prime Factorization
| 709 | 709, 488, 561, 709 |
| 1, 488, 561, 1 |
Multiply the prime numbers at the bottom and the left side.
709 x 1 x 488 x 561 x 1 = 194101512
Therefore, the lowest common multiple of 709,488,561,709 is 194101512.
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.
709 x 488 x 561 x 709 = 137617972008
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.
709 : 1, 709
488 : 1, 2, 4, 8, 61, 122, 244, 488
561 : 1, 3, 11, 17, 33, 51, 187, 561
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,488,561,709, is 1.
Now, the common factors can be found like this.
709:709
488:2x 2x 2x 61
561:3x 11x 17
709:709
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
709 = 709
Therefore, the value for common factors is 709.
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 = 137617972008/(1x709)
LCM = 137617972008/709
LCM = 194101512
Thus, we can understand that the LCM of 709,488,561,709 is 194101512.
