Find LCM of 968,940,636,621,164 with Prime Factorization
2 | 968, 940, 636, 621, 164 |
2 | 484, 470, 318, 621, 82 |
3 | 242, 235, 159, 621, 41 |
242, 235, 53, 207, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 242 x 235 x 53 x 207 x 41 = 306969018840
Therefore, the lowest common multiple of 968,940,636,621,164 is 306969018840.
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.
968 x 940 x 636 x 621 x 164 = 58938051617280
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.
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
621 : 1, 3, 9, 23, 27, 69, 207, 621
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 968,940,636,621,164, is 1.
Now, the common factors can be found like this.
968:2x 2x 2x 11x 11
940:2x 2x 5x 47
636:2x 2x 3x 53
621:3x 3x 3x 23
164:2x 2x 41
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 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 58938051617280/(1x192)
LCM = 58938051617280/192
LCM = 306969018840
Thus, we can understand that the LCM of 968,940,636,621,164 is 306969018840.
