Given numbers are 777,431,862,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,431,862,442 is 148020054.
Find LCM of 777,431,862,442 with Prime Factorization
| 2 | 777, 431, 862, 442 |
| 431 | 777, 431, 431, 221 |
| 777, 1, 1, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 431 x 777 x 1 x 1 x 221 = 148020054
Therefore, the lowest common multiple of 777,431,862,442 is 148020054.
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.
777 x 431 x 862 x 442 = 127593286548
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
431 : 1, 431
862 : 1, 2, 431, 862
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,431,862,442, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
431:431
862:2x 431
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 431 = 862
Therefore, the value for common factors is 862.
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 = 127593286548/(1x862)
LCM = 127593286548/862
LCM = 148020054
Thus, we can understand that the LCM of 777,431,862,442 is 148020054.
