Given numbers are 998,402,681,342,549
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,402,681,342,549 is 158327788842.
Find LCM of 998,402,681,342,549 with Prime Factorization
| 2 | 998, 402, 681, 342, 549 |
| 3 | 499, 201, 681, 171, 549 |
| 3 | 499, 67, 227, 57, 183 |
| 499, 67, 227, 19, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 499 x 67 x 227 x 19 x 61 = 158327788842
Therefore, the lowest common multiple of 998,402,681,342,549 is 158327788842.
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.
998 x 402 x 681 x 342 x 549 = 51298203584808
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.
998 : 1, 2, 499, 998
402 : 1, 2, 3, 6, 67, 134, 201, 402
681 : 1, 3, 227, 681
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,402,681,342,549, is 1.
Now, the common factors can be found like this.
998:2x 499
402:2x 3x 67
681:3x 227
342:2x 3x 3x 19
549:3x 3x 61
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 51298203584808/(1x324)
LCM = 51298203584808/324
LCM = 158327788842
Thus, we can understand that the LCM of 998,402,681,342,549 is 158327788842.
