Given numbers are 921,323,171,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,323,171,969 is 892449.
Find LCM of 921,323,171,969 with Prime Factorization
3 | 921, 323, 171, 969 |
17 | 307, 323, 57, 323 |
19 | 307, 19, 57, 19 |
307, 1, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 19 x 307 x 1 x 3 x 1 = 892449
Therefore, the lowest common multiple of 921,323,171,969 is 892449.
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.
921 x 323 x 171 x 969 = 49292635617
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.
921 : 1, 3, 307, 921
323 : 1, 17, 19, 323
171 : 1, 3, 9, 19, 57, 171
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,323,171,969, is 1.
Now, the common factors can be found like this.
921:3x 307
323:17x 19
171:3x 3x 19
969:3x 17x 19
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 17x 19x 19 = 55233
Therefore, the value for common factors is 55233.
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 = 49292635617/(1x55233)
LCM = 49292635617/55233
LCM = 892449
Thus, we can understand that the LCM of 921,323,171,969 is 892449.
