Given numbers are 251,879,987,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,879,987,707 is 7331281041.
Find LCM of 251,879,987,707 with Prime Factorization
| 3 | 251, 879, 987, 707 |
| 7 | 251, 293, 329, 707 |
| 251, 293, 47, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 251 x 293 x 47 x 101 = 7331281041
Therefore, the lowest common multiple of 251,879,987,707 is 7331281041.
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.
251 x 879 x 987 x 707 = 153956901861
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.
251 : 1, 251
879 : 1, 3, 293, 879
987 : 1, 3, 7, 21, 47, 141, 329, 987
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,879,987,707, is 1.
Now, the common factors can be found like this.
251:251
879:3x 293
987:3x 7x 47
707:7x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 153956901861/(1x21)
LCM = 153956901861/21
LCM = 7331281041
Thus, we can understand that the LCM of 251,879,987,707 is 7331281041.
