Given numbers are 561,991,351,965,130
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,991,351,965,130 is 125539295310.
Find LCM of 561,991,351,965,130 with Prime Factorization
| 3 | 561, 991, 351, 965, 130 |
| 5 | 187, 991, 117, 965, 130 |
| 13 | 187, 991, 117, 193, 26 |
| 187, 991, 9, 193, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 187 x 991 x 9 x 193 x 2 = 125539295310
Therefore, the lowest common multiple of 561,991,351,965,130 is 125539295310.
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.
561 x 991 x 351 x 965 x 130 = 24480162585450
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
991 : 1, 991
351 : 1, 3, 9, 13, 27, 39, 117, 351
965 : 1, 5, 193, 965
130 : 1, 2, 5, 10, 13, 26, 65, 130
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,991,351,965,130, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
991:991
351:3x 3x 3x 13
965:5x 193
130:2x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 24480162585450/(1x195)
LCM = 24480162585450/195
LCM = 125539295310
Thus, we can understand that the LCM of 561,991,351,965,130 is 125539295310.
