Given numbers are 497,145,355,251
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 497,145,355,251 is 18088315.
Find LCM of 497,145,355,251 with Prime Factorization
| 5 | 497, 145, 355, 251 |
| 71 | 497, 29, 71, 251 |
| 7, 29, 1, 251 |
Multiply the prime numbers at the bottom and the left side.
5 x 71 x 7 x 29 x 1 x 251 = 18088315
Therefore, the lowest common multiple of 497,145,355,251 is 18088315.
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.
497 x 145 x 355 x 251 = 6421351825
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.
497 : 1, 7, 71, 497
145 : 1, 5, 29, 145
355 : 1, 5, 71, 355
251 : 1, 251
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,145,355,251, is 1.
Now, the common factors can be found like this.
497:7x 71
145:5x 29
355:5x 71
251:251
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 71 = 355
Therefore, the value for common factors is 355.
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 = 6421351825/(1x355)
LCM = 6421351825/355
LCM = 18088315
Thus, we can understand that the LCM of 497,145,355,251 is 18088315.
