Given numbers are 661,665,494,299
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,665,494,299 is 262859870.
Find LCM of 661,665,494,299 with Prime Factorization
| 13 | 661, 665, 494, 299 |
| 19 | 661, 665, 38, 23 |
| 661, 35, 2, 23 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 661 x 35 x 2 x 23 = 262859870
Therefore, the lowest common multiple of 661,665,494,299 is 262859870.
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.
661 x 665 x 494 x 299 = 64926387890
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.
661 : 1, 661
665 : 1, 5, 7, 19, 35, 95, 133, 665
494 : 1, 2, 13, 19, 26, 38, 247, 494
299 : 1, 13, 23, 299
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,665,494,299, is 1.
Now, the common factors can be found like this.
661:661
665:5x 7x 19
494:2x 13x 19
299:13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 64926387890/(1x247)
LCM = 64926387890/247
LCM = 262859870
Thus, we can understand that the LCM of 661,665,494,299 is 262859870.
