Given numbers are 510,810,785,771,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 510,810,785,771,849 is 157236421590.
Find LCM of 510,810,785,771,849 with Prime Factorization
| 2 | 510, 810, 785, 771, 849 |
| 3 | 255, 405, 785, 771, 849 |
| 5 | 85, 135, 785, 257, 283 |
| 17, 27, 157, 257, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 27 x 157 x 257 x 283 = 157236421590
Therefore, the lowest common multiple of 510,810,785,771,849 is 157236421590.
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.
510 x 810 x 785 x 771 x 849 = 212269169146500
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.
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
785 : 1, 5, 157, 785
771 : 1, 3, 257, 771
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 510,810,785,771,849, is 1.
Now, the common factors can be found like this.
510:2x 3x 5x 17
810:2x 3x 3x 3x 3x 5
785:5x 157
771:3x 257
849:3x 283
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 212269169146500/(1x1350)
LCM = 212269169146500/1350
LCM = 157236421590
Thus, we can understand that the LCM of 510,810,785,771,849 is 157236421590.
