Given numbers are 247,442,892,453,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,442,892,453,505 is 856841137620.
Find LCM of 247,442,892,453,505 with Prime Factorization
| 2 | 247, 442, 892, 453, 505 |
| 13 | 247, 221, 446, 453, 505 |
| 19, 17, 446, 453, 505 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 17 x 446 x 453 x 505 = 856841137620
Therefore, the lowest common multiple of 247,442,892,453,505 is 856841137620.
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.
247 x 442 x 892 x 453 x 505 = 22277869578120
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.
247 : 1, 13, 19, 247
442 : 1, 2, 13, 17, 26, 34, 221, 442
892 : 1, 2, 4, 223, 446, 892
453 : 1, 3, 151, 453
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,442,892,453,505, is 1.
Now, the common factors can be found like this.
247:13x 19
442:2x 13x 17
892:2x 2x 223
453:3x 151
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 22277869578120/(1x26)
LCM = 22277869578120/26
LCM = 856841137620
Thus, we can understand that the LCM of 247,442,892,453,505 is 856841137620.
