Given numbers are 521,274,644,959,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,274,644,959,442 is 10158660148.
Find LCM of 521,274,644,959,442 with Prime Factorization
| 2 | 521, 274, 644, 959, 442 |
| 7 | 521, 137, 322, 959, 221 |
| 137 | 521, 137, 46, 137, 221 |
| 521, 1, 46, 1, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 137 x 521 x 1 x 46 x 1 x 221 = 10158660148
Therefore, the lowest common multiple of 521,274,644,959,442 is 10158660148.
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.
521 x 274 x 644 x 959 x 442 = 38968620327728
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.
521 : 1, 521
274 : 1, 2, 137, 274
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
959 : 1, 7, 137, 959
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,274,644,959,442, is 1.
Now, the common factors can be found like this.
521:521
274:2x 137
644:2x 2x 7x 23
959:7x 137
442:2x 13x 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 2x 7x 137 = 3836
Therefore, the value for common factors is 3836.
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 = 38968620327728/(1x3836)
LCM = 38968620327728/3836
LCM = 10158660148
Thus, we can understand that the LCM of 521,274,644,959,442 is 10158660148.
