Given numbers are 177,748,448,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 177,748,448,979 is 1319723328.
Find LCM of 177,748,448,979 with Prime Factorization
| 2 | 177, 748, 448, 979 |
| 2 | 177, 374, 224, 979 |
| 11 | 177, 187, 112, 979 |
| 177, 17, 112, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 177 x 17 x 112 x 89 = 1319723328
Therefore, the lowest common multiple of 177,748,448,979 is 1319723328.
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.
177 x 748 x 448 x 979 = 58067826432
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.
177 : 1, 3, 59, 177
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,748,448,979, is 1.
Now, the common factors can be found like this.
177:3x 59
748:2x 2x 11x 17
448:2x 2x 2x 2x 2x 2x 7
979:11x 89
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 11 = 44
Therefore, the value for common factors is 44.
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 = 58067826432/(1x44)
LCM = 58067826432/44
LCM = 1319723328
Thus, we can understand that the LCM of 177,748,448,979 is 1319723328.
