Find LCM of 177,544,785,824,721 with Prime Factorization
| 2 | 177, 544, 785, 824, 721 |
| 2 | 177, 272, 785, 412, 721 |
| 2 | 177, 136, 785, 206, 721 |
| 103 | 177, 68, 785, 103, 721 |
| 177, 68, 785, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 103 x 177 x 68 x 785 x 1 x 7 = 54497563680
Therefore, the lowest common multiple of 177,544,785,824,721 is 54497563680.
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 544 x 785 x 824 x 721 = 44905992472320
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
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
785 : 1, 5, 157, 785
824 : 1, 2, 4, 8, 103, 206, 412, 824
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,544,785,824,721, is 1.
Now, the common factors can be found like this.
177:3x 59
544:2x 2x 2x 2x 2x 17
785:5x 157
824:2x 2x 2x 103
721:7x 103
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 103 = 824
Therefore, the value for common factors is 824.
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 = 44905992472320/(1x824)
LCM = 44905992472320/824
LCM = 54497563680
Thus, we can understand that the LCM of 177,544,785,824,721 is 54497563680.
