Given numbers are 706,661,325,280,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 706,661,325,280,642 is 1363178052600.
Find LCM of 706,661,325,280,642 with Prime Factorization
2 | 706, 661, 325, 280, 642 |
5 | 353, 661, 325, 140, 321 |
353, 661, 65, 28, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 353 x 661 x 65 x 28 x 321 = 1363178052600
Therefore, the lowest common multiple of 706,661,325,280,642 is 1363178052600.
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.
706 x 661 x 325 x 280 x 642 = 27263561052000
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.
706 : 1, 2, 353, 706
661 : 1, 661
325 : 1, 5, 13, 25, 65, 325
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,661,325,280,642, is 1.
Now, the common factors can be found like this.
706:2x 353
661:661
325:5x 5x 13
280:2x 2x 2x 5x 7
642:2x 3x 107
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 5 = 20
Therefore, the value for common factors is 20.
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 = 27263561052000/(1x20)
LCM = 27263561052000/20
LCM = 1363178052600
Thus, we can understand that the LCM of 706,661,325,280,642 is 1363178052600.
