Given numbers are 767,978,732,874,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 767,978,732,874,857 is 34273330452348.
Find LCM of 767,978,732,874,857 with Prime Factorization
| 2 | 767, 978, 732, 874, 857 |
| 3 | 767, 489, 366, 437, 857 |
| 767, 163, 122, 437, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 767 x 163 x 122 x 437 x 857 = 34273330452348
Therefore, the lowest common multiple of 767,978,732,874,857 is 34273330452348.
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.
767 x 978 x 732 x 874 x 857 = 411279965428176
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.
767 : 1, 13, 59, 767
978 : 1, 2, 3, 6, 163, 326, 489, 978
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
874 : 1, 2, 19, 23, 38, 46, 437, 874
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 767,978,732,874,857, is 1.
Now, the common factors can be found like this.
767:13x 59
978:2x 3x 163
732:2x 2x 3x 61
874:2x 19x 23
857:857
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 3 = 12
Therefore, the value for common factors is 12.
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 = 411279965428176/(1x12)
LCM = 411279965428176/12
LCM = 34273330452348
Thus, we can understand that the LCM of 767,978,732,874,857 is 34273330452348.
