Given numbers are 561,253,745,535
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,253,745,535 is 1028562645.
Find LCM of 561,253,745,535 with Prime Factorization
| 5 | 561, 253, 745, 535 |
| 11 | 561, 253, 149, 107 |
| 51, 23, 149, 107 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 51 x 23 x 149 x 107 = 1028562645
Therefore, the lowest common multiple of 561,253,745,535 is 1028562645.
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 253 x 745 x 535 = 56570945475
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
253 : 1, 11, 23, 253
745 : 1, 5, 149, 745
535 : 1, 5, 107, 535
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,253,745,535, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
253:11x 23
745:5x 149
535:5x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 56570945475/(1x55)
LCM = 56570945475/55
LCM = 1028562645
Thus, we can understand that the LCM of 561,253,745,535 is 1028562645.
