Given numbers are 975,671,731,289,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 975,671,731,289,777 is 2105684005425.
Find LCM of 975,671,731,289,777 with Prime Factorization
| 3 | 975, 671, 731, 289, 777 |
| 17 | 325, 671, 731, 289, 259 |
| 325, 671, 43, 17, 259 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 325 x 671 x 43 x 17 x 259 = 2105684005425
Therefore, the lowest common multiple of 975,671,731,289,777 is 2105684005425.
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.
975 x 671 x 731 x 289 x 777 = 107389884276675
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
671 : 1, 11, 61, 671
731 : 1, 17, 43, 731
289 : 1, 17, 289
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,671,731,289,777, is 1.
Now, the common factors can be found like this.
975:3x 5x 5x 13
671:11x 61
731:17x 43
289:17x 17
777:3x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 107389884276675/(1x51)
LCM = 107389884276675/51
LCM = 2105684005425
Thus, we can understand that the LCM of 975,671,731,289,777 is 2105684005425.
