Given numbers are 779,980,802,672,682
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,980,802,672,682 is 2505379541280.
Find LCM of 779,980,802,672,682 with Prime Factorization
| 2 | 779, 980, 802, 672, 682 |
| 2 | 779, 490, 401, 336, 341 |
| 7 | 779, 245, 401, 168, 341 |
| 779, 35, 401, 24, 341 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 779 x 35 x 401 x 24 x 341 = 2505379541280
Therefore, the lowest common multiple of 779,980,802,672,682 is 2505379541280.
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 980 x 802 x 672 x 682 = 280602508623360
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
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
802 : 1, 2, 401, 802
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
682 : 1, 2, 11, 22, 31, 62, 341, 682
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,980,802,672,682, is 1.
Now, the common factors can be found like this.
779:19x 41
980:2x 2x 5x 7x 7
802:2x 401
672:2x 2x 2x 2x 2x 3x 7
682:2x 11x 31
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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 280602508623360/(1x112)
LCM = 280602508623360/112
LCM = 2505379541280
Thus, we can understand that the LCM of 779,980,802,672,682 is 2505379541280.
