Find LCM of 561,693,386,887,154 with Prime Factorization
| 2 | 561, 693, 386, 887, 154 |
| 3 | 561, 693, 193, 887, 77 |
| 7 | 187, 231, 193, 887, 77 |
| 11 | 187, 33, 193, 887, 11 |
| 17, 3, 193, 887, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 17 x 3 x 193 x 887 x 1 = 4033602342
Therefore, the lowest common multiple of 561,693,386,887,154 is 4033602342.
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.
561 x 693 x 386 x 887 x 154 = 20498767102044
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
386 : 1, 2, 193, 386
887 : 1, 887
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,693,386,887,154, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
693:3x 3x 7x 11
386:2x 193
887:887
154:2x 7x 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 7x 11x 11 = 5082
Therefore, the value for common factors is 5082.
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 = 20498767102044/(1x5082)
LCM = 20498767102044/5082
LCM = 4033602342
Thus, we can understand that the LCM of 561,693,386,887,154 is 4033602342.
