The LCM of 676,780,779,741 is 7899060.
Find LCM of 676,780,779,741 with Prime Factorization
| 2 | 676, 780, 779, 741 |
| 2 | 338, 390, 779, 741 |
| 3 | 169, 195, 779, 741 |
| 13 | 169, 65, 779, 247 |
| 19 | 13, 5, 779, 19 |
| 13, 5, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 19 x 13 x 5 x 41 x 1 = 7899060
Therefore, the lowest common multiple of 676,780,779,741 is 7899060.
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.
676 x 780 x 779 x 741 = 304366579920
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
779 : 1, 19, 41, 779
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,780,779,741, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
780:2x 2x 3x 5x 13
779:19x 41
741:3x 13x 19
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 13x 13x 19 = 38532
Therefore, the value for common factors is 38532.
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 = 304366579920/(1x38532)
LCM = 304366579920/38532
LCM = 7899060
Thus, we can understand that the LCM of 676,780,779,741 is 7899060.
