Find LCM of 498,154,149,385,685 with Prime Factorization
| 2 | 498, 154, 149, 385, 685 |
| 5 | 249, 77, 149, 385, 685 |
| 7 | 249, 77, 149, 77, 137 |
| 11 | 249, 11, 149, 11, 137 |
| 249, 1, 149, 1, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 249 x 1 x 149 x 1 x 137 = 3913784490
Therefore, the lowest common multiple of 498,154,149,385,685 is 3913784490.
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.
498 x 154 x 149 x 385 x 685 = 3013614057300
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.
498 : 1, 2, 3, 6, 83, 166, 249, 498
154 : 1, 2, 7, 11, 14, 22, 77, 154
149 : 1, 149
385 : 1, 5, 7, 11, 35, 55, 77, 385
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 498,154,149,385,685, is 1.
Now, the common factors can be found like this.
498:2x 3x 83
154:2x 7x 11
149:149
385:5x 7x 11
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 11 = 770
Therefore, the value for common factors is 770.
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 = 3013614057300/(1x770)
LCM = 3013614057300/770
LCM = 3913784490
Thus, we can understand that the LCM of 498,154,149,385,685 is 3913784490.
