Given numbers are 561,442,604,463,787
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,442,604,463,787 is 1605088102332.
Find LCM of 561,442,604,463,787 with Prime Factorization
| 2 | 561, 442, 604, 463, 787 |
| 17 | 561, 221, 302, 463, 787 |
| 33, 13, 302, 463, 787 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 33 x 13 x 302 x 463 x 787 = 1605088102332
Therefore, the lowest common multiple of 561,442,604,463,787 is 1605088102332.
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 442 x 604 x 463 x 787 = 54572995479288
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
442 : 1, 2, 13, 17, 26, 34, 221, 442
604 : 1, 2, 4, 151, 302, 604
463 : 1, 463
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,442,604,463,787, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
442:2x 13x 17
604:2x 2x 151
463:463
787:787
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 54572995479288/(1x34)
LCM = 54572995479288/34
LCM = 1605088102332
Thus, we can understand that the LCM of 561,442,604,463,787 is 1605088102332.
