Given numbers are 77,66,66,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 77,66,66,849 is 130746.
Find LCM of 77,66,66,849 with Prime Factorization
| 2 | 77, 66, 66, 849 |
| 3 | 77, 33, 33, 849 |
| 11 | 77, 11, 11, 283 |
| 7, 1, 1, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 7 x 1 x 1 x 283 = 130746
Therefore, the lowest common multiple of 77,66,66,849 is 130746.
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.
77 x 66 x 66 x 849 = 284764788
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.
77 : 1, 7, 11, 77
66 : 1, 2, 3, 6, 11, 22, 33, 66
66 : 1, 2, 3, 6, 11, 22, 33, 66
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 77,66,66,849, is 1.
Now, the common factors can be found like this.
77:7x 11
66:2x 3x 11
66:2x 3x 11
849:3x 283
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 11x 11 = 2178
Therefore, the value for common factors is 2178.
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 = 284764788/(1x2178)
LCM = 284764788/2178
LCM = 130746
Thus, we can understand that the LCM of 77,66,66,849 is 130746.
