Find LCM of 538,598,198,945,490 with Prime Factorization
| 2 | 538, 598, 198, 945, 490 |
| 3 | 269, 299, 99, 945, 245 |
| 3 | 269, 299, 33, 315, 245 |
| 5 | 269, 299, 11, 105, 245 |
| 7 | 269, 299, 11, 21, 49 |
| 269, 299, 11, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 269 x 299 x 11 x 3 x 7 = 11705123430
Therefore, the lowest common multiple of 538,598,198,945,490 is 11705123430.
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.
538 x 598 x 198 x 945 x 490 = 29496911043600
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.
538 : 1, 2, 269, 538
598 : 1, 2, 13, 23, 26, 46, 299, 598
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,598,198,945,490, is 1.
Now, the common factors can be found like this.
538:2x 269
598:2x 13x 23
198:2x 3x 3x 11
945:3x 3x 3x 5x 7
490:2x 5x 7x 7
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 3x 3x 5x 7 = 2520
Therefore, the value for common factors is 2520.
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 = 29496911043600/(1x2520)
LCM = 29496911043600/2520
LCM = 11705123430
Thus, we can understand that the LCM of 538,598,198,945,490 is 11705123430.
