The LCM of 177,716,721,948,856 is 1544764989432.
Find LCM of 177,716,721,948,856 with Prime Factorization
| 2 | 177, 716, 721, 948, 856 |
| 2 | 177, 358, 721, 474, 428 |
| 3 | 177, 179, 721, 237, 214 |
| 59, 179, 721, 79, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 59 x 179 x 721 x 79 x 214 = 1544764989432
Therefore, the lowest common multiple of 177,716,721,948,856 is 1544764989432.
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 716 x 721 x 948 x 856 = 74148719492736
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
716 : 1, 2, 4, 179, 358, 716
721 : 1, 7, 103, 721
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,716,721,948,856, is 1.
Now, the common factors can be found like this.
177:3x 59
716:2x 2x 179
721:7x 103
948:2x 2x 3x 79
856:2x 2x 2x 107
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 74148719492736/(1x48)
LCM = 74148719492736/48
LCM = 1544764989432
Thus, we can understand that the LCM of 177,716,721,948,856 is 1544764989432.
