Given numbers are 197,239,478,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,239,478,178 is 8380774.
Find LCM of 197,239,478,178 with Prime Factorization
| 2 | 197, 239, 478, 178 |
| 239 | 197, 239, 239, 89 |
| 197, 1, 1, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 239 x 197 x 1 x 1 x 89 = 8380774
Therefore, the lowest common multiple of 197,239,478,178 is 8380774.
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.
197 x 239 x 478 x 178 = 4006009972
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.
197 : 1, 197
239 : 1, 239
478 : 1, 2, 239, 478
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,239,478,178, is 1.
Now, the common factors can be found like this.
197:197
239:239
478:2x 239
178:2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 239 = 478
Therefore, the value for common factors is 478.
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 = 4006009972/(1x478)
LCM = 4006009972/478
LCM = 8380774
Thus, we can understand that the LCM of 197,239,478,178 is 8380774.
