Find LCM of 721,188,927,855,175 with Prime Factorization
| 3 | 721, 188, 927, 855, 175 |
| 3 | 721, 188, 309, 285, 175 |
| 5 | 721, 188, 103, 95, 175 |
| 7 | 721, 188, 103, 19, 35 |
| 103 | 103, 188, 103, 19, 5 |
| 1, 188, 1, 19, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 103 x 1 x 188 x 1 x 19 x 5 = 579467700
Therefore, the lowest common multiple of 721,188,927,855,175 is 579467700.
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.
721 x 188 x 927 x 855 x 175 = 18800829526500
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.
721 : 1, 7, 103, 721
188 : 1, 2, 4, 47, 94, 188
927 : 1, 3, 9, 103, 309, 927
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,188,927,855,175, is 1.
Now, the common factors can be found like this.
721:7x 103
188:2x 2x 47
927:3x 3x 103
855:3x 3x 5x 19
175:5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7x 103 = 32445
Therefore, the value for common factors is 32445.
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 = 18800829526500/(1x32445)
LCM = 18800829526500/32445
LCM = 579467700
Thus, we can understand that the LCM of 721,188,927,855,175 is 579467700.
