Given numbers are 987,919,967,945,581
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,919,967,945,581 is 3276044137485.
Find LCM of 987,919,967,945,581 with Prime Factorization
| 3 | 987, 919, 967, 945, 581 |
| 7 | 329, 919, 967, 315, 581 |
| 47, 919, 967, 45, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 47 x 919 x 967 x 45 x 83 = 3276044137485
Therefore, the lowest common multiple of 987,919,967,945,581 is 3276044137485.
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.
987 x 919 x 967 x 945 x 581 = 481578488210295
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
919 : 1, 919
967 : 1, 967
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,919,967,945,581, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
919:919
967:967
945:3x 3x 3x 5x 7
581:7x 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 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 481578488210295/(1x147)
LCM = 481578488210295/147
LCM = 3276044137485
Thus, we can understand that the LCM of 987,919,967,945,581 is 3276044137485.
