Given numbers are 802,690,579,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,690,579,782 is 907819890.
Find LCM of 802,690,579,782 with Prime Factorization
| 2 | 802, 690, 579, 782 |
| 3 | 401, 345, 579, 391 |
| 23 | 401, 115, 193, 391 |
| 401, 5, 193, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 401 x 5 x 193 x 17 = 907819890
Therefore, the lowest common multiple of 802,690,579,782 is 907819890.
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.
802 x 690 x 579 x 782 = 250558289640
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.
802 : 1, 2, 401, 802
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
579 : 1, 3, 193, 579
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,690,579,782, is 1.
Now, the common factors can be found like this.
802:2x 401
690:2x 3x 5x 23
579:3x 193
782:2x 17x 23
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 23 = 276
Therefore, the value for common factors is 276.
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 = 250558289640/(1x276)
LCM = 250558289640/276
LCM = 907819890
Thus, we can understand that the LCM of 802,690,579,782 is 907819890.
