Given numbers are 706,874,672,760
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 706,874,672,760 is 518316960.
Find LCM of 706,874,672,760 with Prime Factorization
| 2 | 706, 874, 672, 760 |
| 2 | 353, 437, 336, 380 |
| 2 | 353, 437, 168, 190 |
| 19 | 353, 437, 84, 95 |
| 353, 23, 84, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 353 x 23 x 84 x 5 = 518316960
Therefore, the lowest common multiple of 706,874,672,760 is 518316960.
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.
706 x 874 x 672 x 760 = 315136711680
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.
706 : 1, 2, 353, 706
874 : 1, 2, 19, 23, 38, 46, 437, 874
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,874,672,760, is 2.
Now, the common factors can be found like this.
706:2x 353
874:2x 19x 23
672:2x 2x 2x 2x 2x 3x 7
760:2x 2x 2x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 19 = 304
Therefore, the value for common factors is 304.
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 = 315136711680/(2x304)
LCM = 315136711680/608
LCM = 518316960
Thus, we can understand that the LCM of 706,874,672,760 is 518316960.
