Given numbers are 655,715,897,120,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,715,897,120,705 is 2430044760.
Find LCM of 655,715,897,120,705 with Prime Factorization
| 3 | 655, 715, 897, 120, 705 |
| 5 | 655, 715, 299, 40, 235 |
| 13 | 131, 143, 299, 8, 47 |
| 131, 11, 23, 8, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 131 x 11 x 23 x 8 x 47 = 2430044760
Therefore, the lowest common multiple of 655,715,897,120,705 is 2430044760.
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.
655 x 715 x 897 x 120 x 705 = 35539404615000
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.
655 : 1, 5, 131, 655
715 : 1, 5, 11, 13, 55, 65, 143, 715
897 : 1, 3, 13, 23, 39, 69, 299, 897
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,715,897,120,705, is 1.
Now, the common factors can be found like this.
655:5x 131
715:5x 11x 13
897:3x 13x 23
120:2x 2x 2x 3x 5
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 5x 13 = 14625
Therefore, the value for common factors is 14625.
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 = 35539404615000/(1x14625)
LCM = 35539404615000/14625
LCM = 2430044760
Thus, we can understand that the LCM of 655,715,897,120,705 is 2430044760.
