Given numbers are 891,437,975,209,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,437,975,209,618 is 26068120650.
Find LCM of 891,437,975,209,618 with Prime Factorization
| 3 | 891, 437, 975, 209, 618 |
| 11 | 297, 437, 325, 209, 206 |
| 19 | 27, 437, 325, 19, 206 |
| 27, 23, 325, 1, 206 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 19 x 27 x 23 x 325 x 1 x 206 = 26068120650
Therefore, the lowest common multiple of 891,437,975,209,618 is 26068120650.
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.
891 x 437 x 975 x 209 x 618 = 49034134942650
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
437 : 1, 19, 23, 437
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
209 : 1, 11, 19, 209
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 891,437,975,209,618, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
437:19x 23
975:3x 5x 5x 13
209:11x 19
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.
3x 3x 11x 19 = 1881
Therefore, the value for common factors is 1881.
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 = 49034134942650/(1x1881)
LCM = 49034134942650/1881
LCM = 26068120650
Thus, we can understand that the LCM of 891,437,975,209,618 is 26068120650.
