Given numbers are 235,556,668,620,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 235,556,668,620,170 is 11499255940.
Find LCM of 235,556,668,620,170 with Prime Factorization
| 2 | 235, 556, 668, 620, 170 |
| 2 | 235, 278, 334, 310, 85 |
| 5 | 235, 139, 167, 155, 85 |
| 47, 139, 167, 31, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 47 x 139 x 167 x 31 x 17 = 11499255940
Therefore, the lowest common multiple of 235,556,668,620,170 is 11499255940.
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.
235 x 556 x 668 x 620 x 170 = 9199404752000
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.
235 : 1, 5, 47, 235
556 : 1, 2, 4, 139, 278, 556
668 : 1, 2, 4, 167, 334, 668
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 235,556,668,620,170, is 1.
Now, the common factors can be found like this.
235:5x 47
556:2x 2x 139
668:2x 2x 167
620:2x 2x 5x 31
170:2x 5x 17
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 2x 2x 5x 5 = 800
Therefore, the value for common factors is 800.
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 = 9199404752000/(1x800)
LCM = 9199404752000/800
LCM = 11499255940
Thus, we can understand that the LCM of 235,556,668,620,170 is 11499255940.
