Given numbers are 397,610,363,445,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,610,363,445,681 is 1775999465130.
Find LCM of 397,610,363,445,681 with Prime Factorization
| 3 | 397, 610, 363, 445, 681 |
| 5 | 397, 610, 121, 445, 227 |
| 397, 122, 121, 89, 227 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 397 x 122 x 121 x 89 x 227 = 1775999465130
Therefore, the lowest common multiple of 397,610,363,445,681 is 1775999465130.
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.
397 x 610 x 363 x 445 x 681 = 26639991976950
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.
397 : 1, 397
610 : 1, 2, 5, 10, 61, 122, 305, 610
363 : 1, 3, 11, 33, 121, 363
445 : 1, 5, 89, 445
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,610,363,445,681, is 1.
Now, the common factors can be found like this.
397:397
610:2x 5x 61
363:3x 11x 11
445:5x 89
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 5 = 15
Therefore, the value for common factors is 15.
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 = 26639991976950/(1x15)
LCM = 26639991976950/15
LCM = 1775999465130
Thus, we can understand that the LCM of 397,610,363,445,681 is 1775999465130.
