Given numbers are 721,927,763,202,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,927,763,202,172 is 12287232972.
Find LCM of 721,927,763,202,172 with Prime Factorization
| 2 | 721, 927, 763, 202, 172 |
| 7 | 721, 927, 763, 101, 86 |
| 103 | 103, 927, 109, 101, 86 |
| 1, 9, 109, 101, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 103 x 1 x 9 x 109 x 101 x 86 = 12287232972
Therefore, the lowest common multiple of 721,927,763,202,172 is 12287232972.
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 927 x 763 x 202 x 172 = 17718189945624
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
927 : 1, 3, 9, 103, 309, 927
763 : 1, 7, 109, 763
202 : 1, 2, 101, 202
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,927,763,202,172, is 1.
Now, the common factors can be found like this.
721:7x 103
927:3x 3x 103
763:7x 109
202:2x 101
172:2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 103 = 1442
Therefore, the value for common factors is 1442.
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 = 17718189945624/(1x1442)
LCM = 17718189945624/1442
LCM = 12287232972
Thus, we can understand that the LCM of 721,927,763,202,172 is 12287232972.
