Find LCM of 492,987,485,846,789 with Prime Factorization
| 2 | 492, 987, 485, 846, 789 |
| 3 | 246, 987, 485, 423, 789 |
| 47 | 82, 329, 485, 141, 263 |
| 82, 7, 485, 3, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 47 x 82 x 7 x 485 x 3 x 263 = 61941218220
Therefore, the lowest common multiple of 492,987,485,846,789 is 61941218220.
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.
492 x 987 x 485 x 846 x 789 = 157206811842360
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
987 : 1, 3, 7, 21, 47, 141, 329, 987
485 : 1, 5, 97, 485
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,987,485,846,789, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
987:3x 7x 47
485:5x 97
846:2x 3x 3x 47
789:3x 263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 47 = 2538
Therefore, the value for common factors is 2538.
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 = 157206811842360/(1x2538)
LCM = 157206811842360/2538
LCM = 61941218220
Thus, we can understand that the LCM of 492,987,485,846,789 is 61941218220.
