Given numbers are 969,404,618,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,404,618,722 is 766118532.
Find LCM of 969,404,618,722 with Prime Factorization
| 2 | 969, 404, 618, 722 |
| 3 | 969, 202, 309, 361 |
| 19 | 323, 202, 103, 361 |
| 17, 202, 103, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 17 x 202 x 103 x 19 = 766118532
Therefore, the lowest common multiple of 969,404,618,722 is 766118532.
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.
969 x 404 x 618 x 722 = 174675025296
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
404 : 1, 2, 4, 101, 202, 404
618 : 1, 2, 3, 6, 103, 206, 309, 618
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,404,618,722, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
404:2x 2x 101
618:2x 3x 103
722:2x 19x 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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 174675025296/(1x228)
LCM = 174675025296/228
LCM = 766118532
Thus, we can understand that the LCM of 969,404,618,722 is 766118532.
