Given numbers are 493,561,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,561,374 is 32538.
Find LCM of 493,561,374 with Prime Factorization
| 11 | 493, 561, 374 |
| 17 | 493, 51, 34 |
| 29, 3, 2 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 29 x 3 x 2 = 32538
Therefore, the lowest common multiple of 493,561,374 is 32538.
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 561 x 374 = 103438302
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
374 : 1, 2, 11, 17, 22, 34, 187, 374
17 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,561,374, is 17.
Now, the common factors can be found like this.
493:17x 29
561:3x 11x 17
374:2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 103438302/(17x187)
LCM = 103438302/3179
LCM = 32538
Thus, we can understand that the LCM of 493,561,374 is 32538.
