Given numbers are 154,688,989,884,622
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,688,989,884,622 is 83745149488.
Find LCM of 154,688,989,884,622 with Prime Factorization
| 2 | 154, 688, 989, 884, 622 |
| 2 | 77, 344, 989, 442, 311 |
| 43 | 77, 172, 989, 221, 311 |
| 77, 4, 23, 221, 311 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 77 x 4 x 23 x 221 x 311 = 83745149488
Therefore, the lowest common multiple of 154,688,989,884,622 is 83745149488.
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.
154 x 688 x 989 x 884 x 622 = 57616662847744
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
989 : 1, 23, 43, 989
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
622 : 1, 2, 311, 622
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,688,989,884,622, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
688:2x 2x 2x 2x 43
989:23x 43
884:2x 2x 13x 17
622:2x 311
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 43 = 688
Therefore, the value for common factors is 688.
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 = 57616662847744/(1x688)
LCM = 57616662847744/688
LCM = 83745149488
Thus, we can understand that the LCM of 154,688,989,884,622 is 83745149488.
