Given numbers are 521,221,923,497
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,221,923,497 is 57225077.
Find LCM of 521,221,923,497 with Prime Factorization
13 | 521, 221, 923, 497 |
71 | 521, 17, 71, 497 |
521, 17, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
13 x 71 x 521 x 17 x 1 x 7 = 57225077
Therefore, the lowest common multiple of 521,221,923,497 is 57225077.
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.
521 x 221 x 923 x 497 = 52818746071
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.
521 : 1, 521
221 : 1, 13, 17, 221
923 : 1, 13, 71, 923
497 : 1, 7, 71, 497
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,221,923,497, is 1.
Now, the common factors can be found like this.
521:521
221:13x 17
923:13x 71
497:7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 71 = 923
Therefore, the value for common factors is 923.
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 = 52818746071/(1x923)
LCM = 52818746071/923
LCM = 57225077
Thus, we can understand that the LCM of 521,221,923,497 is 57225077.
