| 13 | 52, 3, 91, 1, 11 |
| 4, 3, 7, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 11 x 13 x 4 x 3 x 7 x 1 x 11 = 42810768
Therefore, the lowest common multiple of 624,972,364,242,891 is 42810768.
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.
624 x 972 x 364 x 242 x 891 = 47604204071424
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
242 : 1, 2, 11, 22, 121, 242
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,972,364,242,891, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
972:2x 2x 3x 3x 3x 3x 3
364:2x 2x 7x 13
242:2x 11x 11
891:3x 3x 3x 3x 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 2x 2x 2x 2x 3x 3x 3x 3x 3x 11x 13 = 1111968
Therefore, the value for common factors is 1111968.
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 = 47604204071424/(1x1111968)
LCM = 47604204071424/1111968
LCM = 42810768
Thus, we can understand that the LCM of 624,972,364,242,891 is 42810768.
