Given numbers are 681,562,988,422,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,562,988,422,856 is 8537026018872.
Find LCM of 681,562,988,422,856 with Prime Factorization
| 2 | 681, 562, 988, 422, 856 |
| 2 | 681, 281, 494, 211, 428 |
| 681, 281, 247, 211, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 681 x 281 x 247 x 211 x 214 = 8537026018872
Therefore, the lowest common multiple of 681,562,988,422,856 is 8537026018872.
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.
681 x 562 x 988 x 422 x 856 = 136592416301952
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.
681 : 1, 3, 227, 681
562 : 1, 2, 281, 562
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
422 : 1, 2, 211, 422
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,562,988,422,856, is 1.
Now, the common factors can be found like this.
681:3x 227
562:2x 281
988:2x 2x 13x 19
422:2x 211
856:2x 2x 2x 107
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 136592416301952/(1x16)
LCM = 136592416301952/16
LCM = 8537026018872
Thus, we can understand that the LCM of 681,562,988,422,856 is 8537026018872.
