Given numbers are 620,404,404,823
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,404,404,823 is 51536260.
Find LCM of 620,404,404,823 with Prime Factorization
2 | 620, 404, 404, 823 |
2 | 310, 202, 202, 823 |
101 | 155, 101, 101, 823 |
155, 1, 1, 823 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 155 x 1 x 1 x 823 = 51536260
Therefore, the lowest common multiple of 620,404,404,823 is 51536260.
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.
620 x 404 x 404 x 823 = 83282596160
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
404 : 1, 2, 4, 101, 202, 404
404 : 1, 2, 4, 101, 202, 404
823 : 1, 823
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,404,404,823, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
404:2x 2x 101
404:2x 2x 101
823:823
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 2x 2x 101 = 1616
Therefore, the value for common factors is 1616.
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 = 83282596160/(1x1616)
LCM = 83282596160/1616
LCM = 51536260
Thus, we can understand that the LCM of 620,404,404,823 is 51536260.
