Find LCM of 161,456,381,589,762 with Prime Factorization
| 2 | 161, 456, 381, 589, 762 |
| 3 | 161, 228, 381, 589, 381 |
| 19 | 161, 76, 127, 589, 127 |
| 127 | 161, 4, 127, 31, 127 |
| 161, 4, 1, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 127 x 161 x 4 x 1 x 31 x 1 = 289038792
Therefore, the lowest common multiple of 161,456,381,589,762 is 289038792.
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.
161 x 456 x 381 x 589 x 762 = 12554110891728
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.
161 : 1, 7, 23, 161
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
381 : 1, 3, 127, 381
589 : 1, 19, 31, 589
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,456,381,589,762, is 1.
Now, the common factors can be found like this.
161:7x 23
456:2x 2x 2x 3x 19
381:3x 127
589:19x 31
762:2x 3x 127
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 19x 127 = 43434
Therefore, the value for common factors is 43434.
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 = 12554110891728/(1x43434)
LCM = 12554110891728/43434
LCM = 289038792
Thus, we can understand that the LCM of 161,456,381,589,762 is 289038792.
