Given numbers are 561,194,391,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,194,391,782 is 2503182.
Find LCM of 561,194,391,782 with Prime Factorization
2 | 561, 194, 391, 782 |
17 | 561, 97, 391, 391 |
23 | 33, 97, 23, 23 |
33, 97, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 33 x 97 x 1 x 1 = 2503182
Therefore, the lowest common multiple of 561,194,391,782 is 2503182.
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 194 x 391 x 782 = 33277301508
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
194 : 1, 2, 97, 194
391 : 1, 17, 23, 391
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,194,391,782, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
194:2x 97
391:17x 23
782:2x 17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 17x 23 = 13294
Therefore, the value for common factors is 13294.
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 = 33277301508/(1x13294)
LCM = 33277301508/13294
LCM = 2503182
Thus, we can understand that the LCM of 561,194,391,782 is 2503182.
