Given numbers are 178,121,161,293,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 178,121,161,293,994 is 72136857254.
Find LCM of 178,121,161,293,994 with Prime Factorization
| 2 | 178, 121, 161, 293, 994 |
| 7 | 89, 121, 161, 293, 497 |
| 89, 121, 23, 293, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 89 x 121 x 23 x 293 x 71 = 72136857254
Therefore, the lowest common multiple of 178,121,161,293,994 is 72136857254.
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.
178 x 121 x 161 x 293 x 994 = 1009916001556
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.
178 : 1, 2, 89, 178
121 : 1, 11, 121
161 : 1, 7, 23, 161
293 : 1, 293
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,121,161,293,994, is 1.
Now, the common factors can be found like this.
178:2x 89
121:11x 11
161:7x 23
293:293
994:2x 7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 1009916001556/(1x14)
LCM = 1009916001556/14
LCM = 72136857254
Thus, we can understand that the LCM of 178,121,161,293,994 is 72136857254.
