Given numbers are 779,765,732,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,765,732,648 is 2617346520.
Find LCM of 779,765,732,648 with Prime Factorization
| 2 | 779, 765, 732, 648 |
| 2 | 779, 765, 366, 324 |
| 3 | 779, 765, 183, 162 |
| 3 | 779, 255, 61, 54 |
| 779, 85, 61, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 779 x 85 x 61 x 18 = 2617346520
Therefore, the lowest common multiple of 779,765,732,648 is 2617346520.
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.
779 x 765 x 732 x 648 = 282673424160
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.
779 : 1, 19, 41, 779
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,765,732,648, is 1.
Now, the common factors can be found like this.
779:19x 41
765:3x 3x 5x 17
732:2x 2x 3x 61
648:2x 2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 282673424160/(1x108)
LCM = 282673424160/108
LCM = 2617346520
Thus, we can understand that the LCM of 779,765,732,648 is 2617346520.
