Given numbers are 682,706,420,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,706,420,120 is 101113320.
Find LCM of 682,706,420,120 with Prime Factorization
2 | 682, 706, 420, 120 |
2 | 341, 353, 210, 60 |
3 | 341, 353, 105, 30 |
5 | 341, 353, 35, 10 |
341, 353, 7, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 341 x 353 x 7 x 2 = 101113320
Therefore, the lowest common multiple of 682,706,420,120 is 101113320.
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.
682 x 706 x 420 x 120 = 24267196800
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
706 : 1, 2, 353, 706
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,706,420,120, is 2.
Now, the common factors can be found like this.
682:2x 11x 31
706:2x 353
420:2x 2x 3x 5x 7
120:2x 2x 2x 3x 5
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 24267196800/(2x120)
LCM = 24267196800/240
LCM = 101113320
Thus, we can understand that the LCM of 682,706,420,120 is 101113320.
