Given numbers are 418,380,178,318,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,380,178,318,745 is 8813525820.
Find LCM of 418,380,178,318,745 with Prime Factorization
| 2 | 418, 380, 178, 318, 745 |
| 5 | 209, 190, 89, 159, 745 |
| 19 | 209, 38, 89, 159, 149 |
| 11, 2, 89, 159, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 11 x 2 x 89 x 159 x 149 = 8813525820
Therefore, the lowest common multiple of 418,380,178,318,745 is 8813525820.
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.
418 x 380 x 178 x 318 x 745 = 6698279623200
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
178 : 1, 2, 89, 178
318 : 1, 2, 3, 6, 53, 106, 159, 318
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,380,178,318,745, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
380:2x 2x 5x 19
178:2x 89
318:2x 3x 53
745:5x 149
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 5x 19 = 760
Therefore, the value for common factors is 760.
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 = 6698279623200/(1x760)
LCM = 6698279623200/760
LCM = 8813525820
Thus, we can understand that the LCM of 418,380,178,318,745 is 8813525820.
