Given numbers are 110,721,531,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 110,721,531,618 is 42113610.
Find LCM of 110,721,531,618 with Prime Factorization
| 2 | 110, 721, 531, 618 |
| 3 | 55, 721, 531, 309 |
| 103 | 55, 721, 177, 103 |
| 55, 7, 177, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 55 x 7 x 177 x 1 = 42113610
Therefore, the lowest common multiple of 110,721,531,618 is 42113610.
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.
110 x 721 x 531 x 618 = 26026210980
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.
110 : 1, 2, 5, 10, 11, 22, 55, 110
721 : 1, 7, 103, 721
531 : 1, 3, 9, 59, 177, 531
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 110,721,531,618, is 1.
Now, the common factors can be found like this.
110:2x 5x 11
721:7x 103
531:3x 3x 59
618:2x 3x 103
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 103 = 618
Therefore, the value for common factors is 618.
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 = 26026210980/(1x618)
LCM = 26026210980/618
LCM = 42113610
Thus, we can understand that the LCM of 110,721,531,618 is 42113610.
