Given numbers are 169,702,220,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,702,220,820 is 41158260.
Find LCM of 169,702,220,820 with Prime Factorization
| 2 | 169, 702, 220, 820 |
| 2 | 169, 351, 110, 410 |
| 5 | 169, 351, 55, 205 |
| 13 | 169, 351, 11, 41 |
| 13, 27, 11, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 13 x 27 x 11 x 41 = 41158260
Therefore, the lowest common multiple of 169,702,220,820 is 41158260.
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.
169 x 702 x 220 x 820 = 21402295200
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.
169 : 1, 13, 169
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,702,220,820, is 1.
Now, the common factors can be found like this.
169:13x 13
702:2x 3x 3x 3x 13
220:2x 2x 5x 11
820:2x 2x 5x 41
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 5x 13 = 520
Therefore, the value for common factors is 520.
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 = 21402295200/(1x520)
LCM = 21402295200/520
LCM = 41158260
Thus, we can understand that the LCM of 169,702,220,820 is 41158260.
