Given numbers are 487,959,721,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,959,721,681 is 32759095719.
Find LCM of 487,959,721,681 with Prime Factorization
| 7 | 487, 959, 721, 681 |
| 487, 137, 103, 681 |
Multiply the prime numbers at the bottom and the left side.
7 x 487 x 137 x 103 x 681 = 32759095719
Therefore, the lowest common multiple of 487,959,721,681 is 32759095719.
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.
487 x 959 x 721 x 681 = 229313670033
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.
487 : 1, 487
959 : 1, 7, 137, 959
721 : 1, 7, 103, 721
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,959,721,681, is 1.
Now, the common factors can be found like this.
487:487
959:7x 137
721:7x 103
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 229313670033/(1x7)
LCM = 229313670033/7
LCM = 32759095719
Thus, we can understand that the LCM of 487,959,721,681 is 32759095719.
