Given numbers are 658,745,247,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,745,247,149 is 121081870.
Find LCM of 658,745,247,149 with Prime Factorization
| 149 | 658, 745, 247, 149 |
| 658, 5, 247, 1 |
Multiply the prime numbers at the bottom and the left side.
149 x 658 x 5 x 247 x 1 = 121081870
Therefore, the lowest common multiple of 658,745,247,149 is 121081870.
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.
658 x 745 x 247 x 149 = 18041198630
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
745 : 1, 5, 149, 745
247 : 1, 13, 19, 247
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,745,247,149, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
745:5x 149
247:13x 19
149:149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
149 = 149
Therefore, the value for common factors is 149.
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 = 18041198630/(1x149)
LCM = 18041198630/149
LCM = 121081870
Thus, we can understand that the LCM of 658,745,247,149 is 121081870.
