Given numbers are 278,949,676,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,949,676,403 is 212640532.
Find LCM of 278,949,676,403 with Prime Factorization
| 2 | 278, 949, 676, 403 |
| 13 | 139, 949, 338, 403 |
| 139, 73, 26, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 139 x 73 x 26 x 31 = 212640532
Therefore, the lowest common multiple of 278,949,676,403 is 212640532.
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.
278 x 949 x 676 x 403 = 71872499816
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.
278 : 1, 2, 139, 278
949 : 1, 13, 73, 949
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,949,676,403, is 1.
Now, the common factors can be found like this.
278:2x 139
949:13x 73
676:2x 2x 13x 13
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 71872499816/(1x338)
LCM = 71872499816/338
LCM = 212640532
Thus, we can understand that the LCM of 278,949,676,403 is 212640532.
