Given numbers are 489,715,523,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,715,523,221 is 3108604785.
Find LCM of 489,715,523,221 with Prime Factorization
13 | 489, 715, 523, 221 |
489, 55, 523, 17 |
Multiply the prime numbers at the bottom and the left side.
13 x 489 x 55 x 523 x 17 = 3108604785
Therefore, the lowest common multiple of 489,715,523,221 is 3108604785.
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.
489 x 715 x 523 x 221 = 40411862205
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.
489 : 1, 3, 163, 489
715 : 1, 5, 11, 13, 55, 65, 143, 715
523 : 1, 523
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,715,523,221, is 1.
Now, the common factors can be found like this.
489:3x 163
715:5x 11x 13
523:523
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 40411862205/(1x13)
LCM = 40411862205/13
LCM = 3108604785
Thus, we can understand that the LCM of 489,715,523,221 is 3108604785.
