Given numbers are 427,697,803,644,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,697,803,644,561 is 65960703732.
Find LCM of 427,697,803,644,561 with Prime Factorization
| 7 | 427, 697, 803, 644, 561 |
| 11 | 61, 697, 803, 92, 561 |
| 17 | 61, 697, 73, 92, 51 |
| 61, 41, 73, 92, 3 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 17 x 61 x 41 x 73 x 92 x 3 = 65960703732
Therefore, the lowest common multiple of 427,697,803,644,561 is 65960703732.
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.
427 x 697 x 803 x 644 x 561 = 86342561185188
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.
427 : 1, 7, 61, 427
697 : 1, 17, 41, 697
803 : 1, 11, 73, 803
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,697,803,644,561, is 1.
Now, the common factors can be found like this.
427:7x 61
697:17x 41
803:11x 73
644:2x 2x 7x 23
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 17 = 1309
Therefore, the value for common factors is 1309.
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 = 86342561185188/(1x1309)
LCM = 86342561185188/1309
LCM = 65960703732
Thus, we can understand that the LCM of 427,697,803,644,561 is 65960703732.
