The LCM of 465,156,220,361,169 is 1248244140.
Find LCM of 465,156,220,361,169 with Prime Factorization
| 2 | 465, 156, 220, 361, 169 |
| 2 | 465, 78, 110, 361, 169 |
| 3 | 465, 39, 55, 361, 169 |
| 5 | 155, 13, 55, 361, 169 |
| 13 | 31, 13, 11, 361, 169 |
| 31, 1, 11, 361, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 31 x 1 x 11 x 361 x 13 = 1248244140
Therefore, the lowest common multiple of 465,156,220,361,169 is 1248244140.
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.
465 x 156 x 220 x 361 x 169 = 973630429200
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.
465 : 1, 3, 5, 15, 31, 93, 155, 465
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
361 : 1, 19, 361
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 465,156,220,361,169, is 1.
Now, the common factors can be found like this.
465:3x 5x 31
156:2x 2x 3x 13
220:2x 2x 5x 11
361:19x 19
169:13x 13
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 3x 5x 13 = 780
Therefore, the value for common factors is 780.
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 = 973630429200/(1x780)
LCM = 973630429200/780
LCM = 1248244140
Thus, we can understand that the LCM of 465,156,220,361,169 is 1248244140.
