Find LCM of 971,917,528,168 with Prime Factorization
| 2 | 971, 917, 528, 168 |
| 2 | 971, 917, 264, 84 |
| 2 | 971, 917, 132, 42 |
| 3 | 971, 917, 66, 21 |
| 7 | 971, 917, 22, 7 |
| 971, 131, 22, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 971 x 131 x 22 x 1 = 470134896
Therefore, the lowest common multiple of 971,917,528,168 is 470134896.
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.
971 x 917 x 528 x 168 = 78982662528
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.
971 : 1, 971
917 : 1, 7, 131, 917
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,917,528,168, is 1.
Now, the common factors can be found like this.
971:971
917:7x 131
528:2x 2x 2x 2x 3x 11
168:2x 2x 2x 3x 7
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 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 78982662528/(1x168)
LCM = 78982662528/168
LCM = 470134896
Thus, we can understand that the LCM of 971,917,528,168 is 470134896.
