Given numbers are 493,668,289,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,668,289,221 is 72780604.
Find LCM of 493,668,289,221 with Prime Factorization
17 | 493, 668, 289, 221 |
29, 668, 17, 13 |
Multiply the prime numbers at the bottom and the left side.
17 x 29 x 668 x 17 x 13 = 72780604
Therefore, the lowest common multiple of 493,668,289,221 is 72780604.
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.
493 x 668 x 289 x 221 = 21033594556
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.
493 : 1, 17, 29, 493
668 : 1, 2, 4, 167, 334, 668
289 : 1, 17, 289
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,668,289,221, is 1.
Now, the common factors can be found like this.
493:17x 29
668:2x 2x 167
289:17x 17
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.
17x 17 = 289
Therefore, the value for common factors is 289.
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 = 21033594556/(1x289)
LCM = 21033594556/289
LCM = 72780604
Thus, we can understand that the LCM of 493,668,289,221 is 72780604.
