Given numbers are 771,571,765,575
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,571,765,575 is 12910067325.
Find LCM of 771,571,765,575 with Prime Factorization
| 3 | 771, 571, 765, 575 |
| 5 | 257, 571, 255, 575 |
| 257, 571, 51, 115 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 257 x 571 x 51 x 115 = 12910067325
Therefore, the lowest common multiple of 771,571,765,575 is 12910067325.
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 571 x 765 x 575 = 193651009875
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
571 : 1, 571
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,571,765,575, is 1.
Now, the common factors can be found like this.
771:3x 257
571:571
765:3x 3x 5x 17
575:5x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 193651009875/(1x15)
LCM = 193651009875/15
LCM = 12910067325
Thus, we can understand that the LCM of 771,571,765,575 is 12910067325.
