Given numbers are 278,878,968,173
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,878,968,173 is 10218820744.
Find LCM of 278,878,968,173 with Prime Factorization
| 2 | 278, 878, 968, 173 |
| 139, 439, 484, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 439 x 484 x 173 = 10218820744
Therefore, the lowest common multiple of 278,878,968,173 is 10218820744.
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 878 x 968 x 173 = 40875282976
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
878 : 1, 2, 439, 878
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
173 : 1, 173
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,878,968,173, is 1.
Now, the common factors can be found like this.
278:2x 139
878:2x 439
968:2x 2x 2x 11x 11
173:173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 40875282976/(1x4)
LCM = 40875282976/4
LCM = 10218820744
Thus, we can understand that the LCM of 278,878,968,173 is 10218820744.
