Given numbers are 165,220,973,809,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,220,973,809,545 is 56628074580.
Find LCM of 165,220,973,809,545 with Prime Factorization
| 5 | 165, 220, 973, 809, 545 |
| 11 | 33, 44, 973, 809, 109 |
| 3, 4, 973, 809, 109 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 3 x 4 x 973 x 809 x 109 = 56628074580
Therefore, the lowest common multiple of 165,220,973,809,545 is 56628074580.
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.
165 x 220 x 973 x 809 x 545 = 15572720509500
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
973 : 1, 7, 139, 973
809 : 1, 809
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,220,973,809,545, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
220:2x 2x 5x 11
973:7x 139
809:809
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 11 = 275
Therefore, the value for common factors is 275.
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 = 15572720509500/(1x275)
LCM = 15572720509500/275
LCM = 56628074580
Thus, we can understand that the LCM of 165,220,973,809,545 is 56628074580.
