Find LCM of 891,618,865,972 with Prime Factorization
| 2 | 891, 618, 865, 972 |
| 3 | 891, 309, 865, 486 |
| 3 | 297, 103, 865, 162 |
| 3 | 99, 103, 865, 54 |
| 3 | 33, 103, 865, 18 |
| 11, 103, 865, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 11 x 103 x 865 x 6 = 952603740
Therefore, the lowest common multiple of 891,618,865,972 is 952603740.
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.
891 x 618 x 865 x 972 = 462965417640
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
618 : 1, 2, 3, 6, 103, 206, 309, 618
865 : 1, 5, 173, 865
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,618,865,972, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
618:2x 3x 103
865:5x 173
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 462965417640/(1x486)
LCM = 462965417640/486
LCM = 952603740
Thus, we can understand that the LCM of 891,618,865,972 is 952603740.
