Given numbers are 771,681,477,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,681,477,771 is 27827703.
Find LCM of 771,681,477,771 with Prime Factorization
| 3 | 771, 681, 477, 771 |
| 257 | 257, 227, 159, 257 |
| 1, 227, 159, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 257 x 1 x 227 x 159 x 1 = 27827703
Therefore, the lowest common multiple of 771,681,477,771 is 27827703.
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.
771 x 681 x 477 x 771 = 193096431117
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.
771 : 1, 3, 257, 771
681 : 1, 3, 227, 681
477 : 1, 3, 9, 53, 159, 477
771 : 1, 3, 257, 771
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,681,477,771, is 3.
Now, the common factors can be found like this.
771:3x 257
681:3x 227
477:3x 3x 53
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 257 = 2313
Therefore, the value for common factors is 2313.
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 = 193096431117/(3x2313)
LCM = 193096431117/6939
LCM = 27827703
Thus, we can understand that the LCM of 771,681,477,771 is 27827703.
