Given numbers are 828,561,347,255,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 828,561,347,255,681 is 60981384420.
Find LCM of 828,561,347,255,681 with Prime Factorization
| 3 | 828, 561, 347, 255, 681 |
| 17 | 276, 187, 347, 85, 227 |
| 276, 11, 347, 5, 227 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 276 x 11 x 347 x 5 x 227 = 60981384420
Therefore, the lowest common multiple of 828,561,347,255,681 is 60981384420.
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.
828 x 561 x 347 x 255 x 681 = 27990455448780
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
561 : 1, 3, 11, 17, 33, 51, 187, 561
347 : 1, 347
255 : 1, 3, 5, 15, 17, 51, 85, 255
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,561,347,255,681, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
561:3x 11x 17
347:347
255:3x 5x 17
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.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 27990455448780/(1x459)
LCM = 27990455448780/459
LCM = 60981384420
Thus, we can understand that the LCM of 828,561,347,255,681 is 60981384420.
