Given numbers are 771,866,390,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,866,390,771 is 43399590.
Find LCM of 771,866,390,771 with Prime Factorization
| 2 | 771, 866, 390, 771 |
| 3 | 771, 433, 195, 771 |
| 257 | 257, 433, 65, 257 |
| 1, 433, 65, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 257 x 1 x 433 x 65 x 1 = 43399590
Therefore, the lowest common multiple of 771,866,390,771 is 43399590.
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 866 x 390 x 771 = 200766503340
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
866 : 1, 2, 433, 866
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,866,390,771, is 1.
Now, the common factors can be found like this.
771:3x 257
866:2x 433
390:2x 3x 5x 13
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.
2x 3x 3x 257 = 4626
Therefore, the value for common factors is 4626.
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 = 200766503340/(1x4626)
LCM = 200766503340/4626
LCM = 43399590
Thus, we can understand that the LCM of 771,866,390,771 is 43399590.
