Given numbers are 103,147,927,430,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,147,927,430,721 is 19531890.
Find LCM of 103,147,927,430,721 with Prime Factorization
| 3 | 103, 147, 927, 430, 721 |
| 7 | 103, 49, 309, 430, 721 |
| 103 | 103, 7, 309, 430, 103 |
| 1, 7, 3, 430, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 103 x 1 x 7 x 3 x 430 x 1 = 19531890
Therefore, the lowest common multiple of 103,147,927,430,721 is 19531890.
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.
103 x 147 x 927 x 430 x 721 = 4351490241210
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.
103 : 1, 103
147 : 1, 3, 7, 21, 49, 147
927 : 1, 3, 9, 103, 309, 927
430 : 1, 2, 5, 10, 43, 86, 215, 430
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,147,927,430,721, is 1.
Now, the common factors can be found like this.
103:103
147:3x 7x 7
927:3x 3x 103
430:2x 5x 43
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.
3x 7x 103x 103 = 222789
Therefore, the value for common factors is 222789.
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 = 4351490241210/(1x222789)
LCM = 4351490241210/222789
LCM = 19531890
Thus, we can understand that the LCM of 103,147,927,430,721 is 19531890.
