Given numbers are 771,201,301,644,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,201,301,644,809 is 1157262885996.
Find LCM of 771,201,301,644,809 with Prime Factorization
| 3 | 771, 201, 301, 644, 809 |
| 7 | 257, 67, 301, 644, 809 |
| 257, 67, 43, 92, 809 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 257 x 67 x 43 x 92 x 809 = 1157262885996
Therefore, the lowest common multiple of 771,201,301,644,809 is 1157262885996.
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.
771 x 201 x 301 x 644 x 809 = 24302520605916
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.
771 : 1, 3, 257, 771
201 : 1, 3, 67, 201
301 : 1, 7, 43, 301
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,201,301,644,809, is 1.
Now, the common factors can be found like this.
771:3x 257
201:3x 67
301:7x 43
644:2x 2x 7x 23
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 24302520605916/(1x21)
LCM = 24302520605916/21
LCM = 1157262885996
Thus, we can understand that the LCM of 771,201,301,644,809 is 1157262885996.
