Find LCM of 243,152,456,494,985 with Prime Factorization
| 2 | 243, 152, 456, 494, 985 |
| 2 | 243, 76, 228, 247, 985 |
| 2 | 243, 38, 114, 247, 985 |
| 3 | 243, 19, 57, 247, 985 |
| 19 | 81, 19, 19, 247, 985 |
| 81, 1, 1, 13, 985 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 81 x 1 x 1 x 13 x 985 = 472965480
Therefore, the lowest common multiple of 243,152,456,494,985 is 472965480.
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.
243 x 152 x 456 x 494 x 985 = 8195545837440
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.
243 : 1, 3, 9, 27, 81, 243
152 : 1, 2, 4, 8, 19, 38, 76, 152
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
494 : 1, 2, 13, 19, 26, 38, 247, 494
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,152,456,494,985, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
152:2x 2x 2x 19
456:2x 2x 2x 3x 19
494:2x 13x 19
985:5x 197
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 2x 3x 19x 19 = 17328
Therefore, the value for common factors is 17328.
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 = 8195545837440/(1x17328)
LCM = 8195545837440/17328
LCM = 472965480
Thus, we can understand that the LCM of 243,152,456,494,985 is 472965480.
