Given numbers are 354,789,431,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 354,789,431,856 is 17174339736.
Find LCM of 354,789,431,856 with Prime Factorization
| 2 | 354, 789, 431, 856 |
| 3 | 177, 789, 431, 428 |
| 59, 263, 431, 428 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 59 x 263 x 431 x 428 = 17174339736
Therefore, the lowest common multiple of 354,789,431,856 is 17174339736.
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.
354 x 789 x 431 x 856 = 103046038416
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.
354 : 1, 2, 3, 6, 59, 118, 177, 354
789 : 1, 3, 263, 789
431 : 1, 431
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,789,431,856, is 1.
Now, the common factors can be found like this.
354:2x 3x 59
789:3x 263
431:431
856:2x 2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 103046038416/(1x6)
LCM = 103046038416/6
LCM = 17174339736
Thus, we can understand that the LCM of 354,789,431,856 is 17174339736.
