Given numbers are 502,138,644,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 502,138,644,897 is 6304116.
Find LCM of 502,138,644,897 with Prime Factorization
| 2 | 502, 138, 644, 897 |
| 3 | 251, 69, 322, 897 |
| 23 | 251, 23, 322, 299 |
| 251, 1, 14, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 251 x 1 x 14 x 13 = 6304116
Therefore, the lowest common multiple of 502,138,644,897 is 6304116.
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.
502 x 138 x 644 x 897 = 40018528368
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.
502 : 1, 2, 251, 502
138 : 1, 2, 3, 6, 23, 46, 69, 138
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 502,138,644,897, is 1.
Now, the common factors can be found like this.
502:2x 251
138:2x 3x 23
644:2x 2x 7x 23
897:3x 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.
2x 2x 3x 23x 23 = 6348
Therefore, the value for common factors is 6348.
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 = 40018528368/(1x6348)
LCM = 40018528368/6348
LCM = 6304116
Thus, we can understand that the LCM of 502,138,644,897 is 6304116.
