Given numbers are 427,217,727,170,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,217,727,170,660 is 107973414780.
Find LCM of 427,217,727,170,660 with Prime Factorization
2 | 427, 217, 727, 170, 660 |
5 | 427, 217, 727, 85, 330 |
7 | 427, 217, 727, 17, 66 |
61, 31, 727, 17, 66 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 61 x 31 x 727 x 17 x 66 = 107973414780
Therefore, the lowest common multiple of 427,217,727,170,660 is 107973414780.
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.
427 x 217 x 727 x 170 x 660 = 7558139034600
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.
427 : 1, 7, 61, 427
217 : 1, 7, 31, 217
727 : 1, 727
170 : 1, 2, 5, 10, 17, 34, 85, 170
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,217,727,170,660, is 1.
Now, the common factors can be found like this.
427:7x 61
217:7x 31
727:727
170:2x 5x 17
660:2x 2x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 7558139034600/(1x70)
LCM = 7558139034600/70
LCM = 107973414780
Thus, we can understand that the LCM of 427,217,727,170,660 is 107973414780.
