Given numbers are 771,477,985,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,477,985,197 is 120750165.
Find LCM of 771,477,985,197 with Prime Factorization
| 3 | 771, 477, 985, 197 |
| 197 | 257, 159, 985, 197 |
| 257, 159, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 197 x 257 x 159 x 5 x 1 = 120750165
Therefore, the lowest common multiple of 771,477,985,197 is 120750165.
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 477 x 985 x 197 = 71363347515
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
477 : 1, 3, 9, 53, 159, 477
985 : 1, 5, 197, 985
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,477,985,197, is 1.
Now, the common factors can be found like this.
771:3x 257
477:3x 3x 53
985:5x 197
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 197 = 591
Therefore, the value for common factors is 591.
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 = 71363347515/(1x591)
LCM = 71363347515/591
LCM = 120750165
Thus, we can understand that the LCM of 771,477,985,197 is 120750165.
