Find LCM of 493,498,746,945,189 with Prime Factorization
| 2 | 493, 498, 746, 945, 189 |
| 3 | 493, 249, 373, 945, 189 |
| 3 | 493, 83, 373, 315, 63 |
| 3 | 493, 83, 373, 105, 21 |
| 7 | 493, 83, 373, 35, 7 |
| 493, 83, 373, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 493 x 83 x 373 x 5 x 1 = 28846667430
Therefore, the lowest common multiple of 493,498,746,945,189 is 28846667430.
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.
493 x 498 x 746 x 945 x 189 = 32712120865620
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.
493 : 1, 17, 29, 493
498 : 1, 2, 3, 6, 83, 166, 249, 498
746 : 1, 2, 373, 746
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,498,746,945,189, is 1.
Now, the common factors can be found like this.
493:17x 29
498:2x 3x 83
746:2x 373
945:3x 3x 3x 5x 7
189:3x 3x 3x 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 3x 3x 3x 3x 7 = 1134
Therefore, the value for common factors is 1134.
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 = 32712120865620/(1x1134)
LCM = 32712120865620/1134
LCM = 28846667430
Thus, we can understand that the LCM of 493,498,746,945,189 is 28846667430.
