Find LCM of 978,345,575,454,161 with Prime Factorization
2 | 978, 345, 575, 454, 161 |
3 | 489, 345, 575, 227, 161 |
5 | 163, 115, 575, 227, 161 |
23 | 163, 23, 115, 227, 161 |
163, 1, 5, 227, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 163 x 1 x 5 x 227 x 7 = 893574150
Therefore, the lowest common multiple of 978,345,575,454,161 is 893574150.
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.
978 x 345 x 575 x 454 x 161 = 14181021760500
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
345 : 1, 3, 5, 15, 23, 69, 115, 345
575 : 1, 5, 23, 25, 115, 575
454 : 1, 2, 227, 454
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,345,575,454,161, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
345:3x 5x 23
575:5x 5x 23
454:2x 227
161:7x 23
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 5x 23x 23 = 15870
Therefore, the value for common factors is 15870.
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 = 14181021760500/(1x15870)
LCM = 14181021760500/15870
LCM = 893574150
Thus, we can understand that the LCM of 978,345,575,454,161 is 893574150.
