The LCM of 779,765,442,423 is 728232570.
Find LCM of 779,765,442,423 with Prime Factorization
| 3 | 779, 765, 442, 423 |
| 3 | 779, 255, 442, 141 |
| 17 | 779, 85, 442, 47 |
| 779, 5, 26, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 779 x 5 x 26 x 47 = 728232570
Therefore, the lowest common multiple of 779,765,442,423 is 728232570.
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 442 x 423 = 111419583210
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
442 : 1, 2, 13, 17, 26, 34, 221, 442
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,765,442,423, is 1.
Now, the common factors can be found like this.
779:19x 41
765:3x 3x 5x 17
442:2x 13x 17
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17 = 153
Therefore, the value for common factors is 153.
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 = 111419583210/(1x153)
LCM = 111419583210/153
LCM = 728232570
Thus, we can understand that the LCM of 779,765,442,423 is 728232570.
