Given numbers are 921,61,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,61,984 is 18427368.
Find LCM of 921,61,984 with Prime Factorization
3 | 921, 61, 984 |
307, 61, 328 |
Multiply the prime numbers at the bottom and the left side.
3 x 307 x 61 x 328 = 18427368
Therefore, the lowest common multiple of 921,61,984 is 18427368.
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 61 x 984 = 55282104
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
61 : 1, 61
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,61,984, is 1.
Now, the common factors can be found like this.
921:3x 307
61:61
984:2x 2x 2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 55282104/(1x3)
LCM = 55282104/3
LCM = 18427368
Thus, we can understand that the LCM of 921,61,984 is 18427368.
