Given numbers are 170,705,890,712
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 170,705,890,712 is 8533320.
Find LCM of 170,705,890,712 with Prime Factorization
2 | 170, 705, 890, 712 |
5 | 85, 705, 445, 356 |
89 | 17, 141, 89, 356 |
17, 141, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 89 x 17 x 141 x 1 x 4 = 8533320
Therefore, the lowest common multiple of 170,705,890,712 is 8533320.
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.
170 x 705 x 890 x 712 = 75946548000
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
705 : 1, 3, 5, 15, 47, 141, 235, 705
890 : 1, 2, 5, 10, 89, 178, 445, 890
712 : 1, 2, 4, 8, 89, 178, 356, 712
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,705,890,712, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
705:3x 5x 47
890:2x 5x 89
712:2x 2x 2x 89
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 5x 5x 89 = 8900
Therefore, the value for common factors is 8900.
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 = 75946548000/(1x8900)
LCM = 75946548000/8900
LCM = 8533320
Thus, we can understand that the LCM of 170,705,890,712 is 8533320.
