Find LCM of 161,170,630,351,403 with Prime Factorization
2 | 161, 170, 630, 351, 403 |
3 | 161, 85, 315, 351, 403 |
3 | 161, 85, 105, 117, 403 |
5 | 161, 85, 35, 39, 403 |
7 | 161, 17, 7, 39, 403 |
13 | 23, 17, 1, 39, 403 |
23, 17, 1, 3, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 13 x 23 x 17 x 1 x 3 x 31 = 297812970
Therefore, the lowest common multiple of 161,170,630,351,403 is 297812970.
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 170 x 630 x 351 x 403 = 2439088224300
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
351 : 1, 3, 9, 13, 27, 39, 117, 351
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,170,630,351,403, is 1.
Now, the common factors can be found like this.
161:7x 23
170:2x 5x 17
630:2x 3x 3x 5x 7
351:3x 3x 3x 13
403:13x 31
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 5x 7x 13 = 8190
Therefore, the value for common factors is 8190.
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 = 2439088224300/(1x8190)
LCM = 2439088224300/8190
LCM = 297812970
Thus, we can understand that the LCM of 161,170,630,351,403 is 297812970.
