Given numbers are 861,209,181,803,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,209,181,803,172 is 408958575564.
Find LCM of 861,209,181,803,172 with Prime Factorization
11 | 861, 209, 181, 803, 172 |
861, 19, 181, 73, 172 |
Multiply the prime numbers at the bottom and the left side.
11 x 861 x 19 x 181 x 73 x 172 = 408958575564
Therefore, the lowest common multiple of 861,209,181,803,172 is 408958575564.
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.
861 x 209 x 181 x 803 x 172 = 4498544331204
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
209 : 1, 11, 19, 209
181 : 1, 181
803 : 1, 11, 73, 803
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 861,209,181,803,172, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
209:11x 19
181:181
803:11x 73
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.
11 = 11
Therefore, the value for common factors is 11.
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 = 4498544331204/(1x11)
LCM = 4498544331204/11
LCM = 408958575564
Thus, we can understand that the LCM of 861,209,181,803,172 is 408958575564.
