Given numbers are 689,245,416,579
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,245,416,579 is 3127619040.
Find LCM of 689,245,416,579 with Prime Factorization
13 | 689, 245, 416, 579 |
53, 245, 32, 579 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 245 x 32 x 579 = 3127619040
Therefore, the lowest common multiple of 689,245,416,579 is 3127619040.
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.
689 x 245 x 416 x 579 = 40659047520
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.
689 : 1, 13, 53, 689
245 : 1, 5, 7, 35, 49, 245
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
579 : 1, 3, 193, 579
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,245,416,579, is 1.
Now, the common factors can be found like this.
689:13x 53
245:5x 7x 7
416:2x 2x 2x 2x 2x 13
579:3x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 40659047520/(1x13)
LCM = 40659047520/13
LCM = 3127619040
Thus, we can understand that the LCM of 689,245,416,579 is 3127619040.
