Given numbers are 242,878,374,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 242,878,374,902 is 74047886.
Find LCM of 242,878,374,902 with Prime Factorization
| 2 | 242, 878, 374, 902 |
| 11 | 121, 439, 187, 451 |
| 11, 439, 17, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 439 x 17 x 41 = 74047886
Therefore, the lowest common multiple of 242,878,374,902 is 74047886.
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.
242 x 878 x 374 x 902 = 71678353648
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.
242 : 1, 2, 11, 22, 121, 242
878 : 1, 2, 439, 878
374 : 1, 2, 11, 17, 22, 34, 187, 374
902 : 1, 2, 11, 22, 41, 82, 451, 902
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,878,374,902, is 2.
Now, the common factors can be found like this.
242:2x 11x 11
878:2x 439
374:2x 11x 17
902:2x 11x 41
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 71678353648/(2x484)
LCM = 71678353648/968
LCM = 74047886
Thus, we can understand that the LCM of 242,878,374,902 is 74047886.
