Given numbers are 770,660,547
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,660,547 is 2527140.
Find LCM of 770,660,547 with Prime Factorization
| 2 | 770, 660, 547 |
| 5 | 385, 330, 547 |
| 11 | 77, 66, 547 |
| 7, 6, 547 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 7 x 6 x 547 = 2527140
Therefore, the lowest common multiple of 770,660,547 is 2527140.
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.
770 x 660 x 547 = 277985400
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
547 : 1, 547
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,660,547, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
660:2x 2x 3x 5x 11
547:547
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 277985400/(1x110)
LCM = 277985400/110
LCM = 2527140
Thus, we can understand that the LCM of 770,660,547 is 2527140.
