Find LCM of 105,167,652,987,990 with Prime Factorization
2 | 105, 167, 652, 987, 990 |
3 | 105, 167, 326, 987, 495 |
5 | 35, 167, 326, 329, 165 |
7 | 7, 167, 326, 329, 33 |
1, 167, 326, 47, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 1 x 167 x 326 x 47 x 33 = 17732303820
Therefore, the lowest common multiple of 105,167,652,987,990 is 17732303820.
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.
105 x 167 x 652 x 987 x 990 = 11171351406600
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
167 : 1, 167
652 : 1, 2, 4, 163, 326, 652
987 : 1, 3, 7, 21, 47, 141, 329, 987
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,167,652,987,990, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
167:167
652:2x 2x 163
987:3x 7x 47
990:2x 3x 3x 5x 11
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 7 = 630
Therefore, the value for common factors is 630.
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 = 11171351406600/(1x630)
LCM = 11171351406600/630
LCM = 17732303820
Thus, we can understand that the LCM of 105,167,652,987,990 is 17732303820.
