Find LCM of 161,874,518,978,657 with Prime Factorization
| 2 | 161, 874, 518, 978, 657 |
| 3 | 161, 437, 259, 489, 657 |
| 7 | 161, 437, 259, 163, 219 |
| 23 | 23, 437, 37, 163, 219 |
| 1, 19, 37, 163, 219 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 1 x 19 x 37 x 163 x 219 = 24241761306
Therefore, the lowest common multiple of 161,874,518,978,657 is 24241761306.
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 874 x 518 x 978 x 657 = 46835082843192
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
874 : 1, 2, 19, 23, 38, 46, 437, 874
518 : 1, 2, 7, 14, 37, 74, 259, 518
978 : 1, 2, 3, 6, 163, 326, 489, 978
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,874,518,978,657, is 1.
Now, the common factors can be found like this.
161:7x 23
874:2x 19x 23
518:2x 7x 37
978:2x 3x 163
657:3x 3x 73
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 7x 23 = 1932
Therefore, the value for common factors is 1932.
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 = 46835082843192/(1x1932)
LCM = 46835082843192/1932
LCM = 24241761306
Thus, we can understand that the LCM of 161,874,518,978,657 is 24241761306.
