Given numbers are 265,610,561,871,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 265,610,561,871,172 is 1358579859780.
Find LCM of 265,610,561,871,172 with Prime Factorization
| 2 | 265, 610, 561, 871, 172 |
| 5 | 265, 305, 561, 871, 86 |
| 53, 61, 561, 871, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 53 x 61 x 561 x 871 x 86 = 1358579859780
Therefore, the lowest common multiple of 265,610,561,871,172 is 1358579859780.
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.
265 x 610 x 561 x 871 x 172 = 13585798597800
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.
265 : 1, 5, 53, 265
610 : 1, 2, 5, 10, 61, 122, 305, 610
561 : 1, 3, 11, 17, 33, 51, 187, 561
871 : 1, 13, 67, 871
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 265,610,561,871,172, is 1.
Now, the common factors can be found like this.
265:5x 53
610:2x 5x 61
561:3x 11x 17
871:13x 67
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 5 = 10
Therefore, the value for common factors is 10.
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 = 13585798597800/(1x10)
LCM = 13585798597800/10
LCM = 1358579859780
Thus, we can understand that the LCM of 265,610,561,871,172 is 1358579859780.
