Given numbers are 545,663,442,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,663,442,691 is 499364970.
Find LCM of 545,663,442,691 with Prime Factorization
13 | 545, 663, 442, 691 |
17 | 545, 51, 34, 691 |
545, 3, 2, 691 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 545 x 3 x 2 x 691 = 499364970
Therefore, the lowest common multiple of 545,663,442,691 is 499364970.
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.
545 x 663 x 442 x 691 = 110359658370
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.
545 : 1, 5, 109, 545
663 : 1, 3, 13, 17, 39, 51, 221, 663
442 : 1, 2, 13, 17, 26, 34, 221, 442
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,663,442,691, is 1.
Now, the common factors can be found like this.
545:5x 109
663:3x 13x 17
442:2x 13x 17
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 110359658370/(1x221)
LCM = 110359658370/221
LCM = 499364970
Thus, we can understand that the LCM of 545,663,442,691 is 499364970.
