Given numbers are 861,520,506,363,353
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,520,506,363,353 is 439839680280.
Find LCM of 861,520,506,363,353 with Prime Factorization
| 2 | 861, 520, 506, 363, 353 |
| 3 | 861, 260, 253, 363, 353 |
| 11 | 287, 260, 253, 121, 353 |
| 287, 260, 23, 11, 353 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 287 x 260 x 23 x 11 x 353 = 439839680280
Therefore, the lowest common multiple of 861,520,506,363,353 is 439839680280.
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.
861 x 520 x 506 x 363 x 353 = 29029418898480
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
506 : 1, 2, 11, 22, 23, 46, 253, 506
363 : 1, 3, 11, 33, 121, 363
353 : 1, 353
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,520,506,363,353, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
520:2x 2x 2x 5x 13
506:2x 11x 23
363:3x 11x 11
353:353
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 11 = 66
Therefore, the value for common factors is 66.
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 = 29029418898480/(1x66)
LCM = 29029418898480/66
LCM = 439839680280
Thus, we can understand that the LCM of 861,520,506,363,353 is 439839680280.
