Given numbers are 781,369,762,779,481
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,369,762,779,481 is 668974854834.
Find LCM of 781,369,762,779,481 with Prime Factorization
| 3 | 781, 369, 762, 779, 481 |
| 41 | 781, 123, 254, 779, 481 |
| 781, 3, 254, 19, 481 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 781 x 3 x 254 x 19 x 481 = 668974854834
Therefore, the lowest common multiple of 781,369,762,779,481 is 668974854834.
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.
781 x 369 x 762 x 779 x 481 = 82283907144582
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.
781 : 1, 11, 71, 781
369 : 1, 3, 9, 41, 123, 369
762 : 1, 2, 3, 6, 127, 254, 381, 762
779 : 1, 19, 41, 779
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,369,762,779,481, is 1.
Now, the common factors can be found like this.
781:11x 71
369:3x 3x 41
762:2x 3x 127
779:19x 41
481:13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 82283907144582/(1x123)
LCM = 82283907144582/123
LCM = 668974854834
Thus, we can understand that the LCM of 781,369,762,779,481 is 668974854834.
