Given numbers are 862,878,904,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,878,904,452 is 171044936.
Find LCM of 862,878,904,452 with Prime Factorization
| 2 | 862, 878, 904, 452 |
| 2 | 431, 439, 452, 226 |
| 113 | 431, 439, 113, 226 |
| 431, 439, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 113 x 431 x 439 x 1 x 2 = 171044936
Therefore, the lowest common multiple of 862,878,904,452 is 171044936.
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.
862 x 878 x 904 x 452 = 309249244288
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.
862 : 1, 2, 431, 862
878 : 1, 2, 439, 878
904 : 1, 2, 4, 8, 113, 226, 452, 904
452 : 1, 2, 4, 113, 226, 452
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,878,904,452, is 2.
Now, the common factors can be found like this.
862:2x 431
878:2x 439
904:2x 2x 2x 113
452:2x 2x 113
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 2x 113 = 904
Therefore, the value for common factors is 904.
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 = 309249244288/(2x904)
LCM = 309249244288/1808
LCM = 171044936
Thus, we can understand that the LCM of 862,878,904,452 is 171044936.
