Given numbers are 171,220,370,605,853
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,220,370,605,853 is 13060573020.
Find LCM of 171,220,370,605,853 with Prime Factorization
| 2 | 171, 220, 370, 605, 853 |
| 5 | 171, 110, 185, 605, 853 |
| 11 | 171, 22, 37, 121, 853 |
| 171, 2, 37, 11, 853 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 171 x 2 x 37 x 11 x 853 = 13060573020
Therefore, the lowest common multiple of 171,220,370,605,853 is 13060573020.
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.
171 x 220 x 370 x 605 x 853 = 7183315161000
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.
171 : 1, 3, 9, 19, 57, 171
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
370 : 1, 2, 5, 10, 37, 74, 185, 370
605 : 1, 5, 11, 55, 121, 605
853 : 1, 853
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,220,370,605,853, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
220:2x 2x 5x 11
370:2x 5x 37
605:5x 11x 11
853:853
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 5x 11 = 550
Therefore, the value for common factors is 550.
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 = 7183315161000/(1x550)
LCM = 7183315161000/550
LCM = 13060573020
Thus, we can understand that the LCM of 171,220,370,605,853 is 13060573020.
