Find LCM of 868,402,242,561,340 with Prime Factorization
| 2 | 868, 402, 242, 561, 340 |
| 2 | 434, 201, 121, 561, 170 |
| 3 | 217, 201, 121, 561, 85 |
| 11 | 217, 67, 121, 187, 85 |
| 17 | 217, 67, 11, 17, 85 |
| 217, 67, 11, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 217 x 67 x 11 x 1 x 5 = 1794403380
Therefore, the lowest common multiple of 868,402,242,561,340 is 1794403380.
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.
868 x 402 x 242 x 561 x 340 = 16106564738880
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
402 : 1, 2, 3, 6, 67, 134, 201, 402
242 : 1, 2, 11, 22, 121, 242
561 : 1, 3, 11, 17, 33, 51, 187, 561
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,402,242,561,340, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
402:2x 3x 67
242:2x 11x 11
561:3x 11x 17
340:2x 2x 5x 17
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 3x 11x 17 = 8976
Therefore, the value for common factors is 8976.
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 = 16106564738880/(1x8976)
LCM = 16106564738880/8976
LCM = 1794403380
Thus, we can understand that the LCM of 868,402,242,561,340 is 1794403380.
