Given numbers are 156,747,986,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 156,747,986,897 is 440452116.
Find LCM of 156,747,986,897 with Prime Factorization
| 2 | 156, 747, 986, 897 |
| 3 | 78, 747, 493, 897 |
| 13 | 26, 249, 493, 299 |
| 2, 249, 493, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 2 x 249 x 493 x 23 = 440452116
Therefore, the lowest common multiple of 156,747,986,897 is 440452116.
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.
156 x 747 x 986 x 897 = 103065795144
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
747 : 1, 3, 9, 83, 249, 747
986 : 1, 2, 17, 29, 34, 58, 493, 986
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,747,986,897, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
747:3x 3x 83
986:2x 17x 29
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 103065795144/(1x234)
LCM = 103065795144/234
LCM = 440452116
Thus, we can understand that the LCM of 156,747,986,897 is 440452116.
