The LCM of 449,497,426,654 is 145942062.
Find LCM of 449,497,426,654 with Prime Factorization
| 2 | 449, 497, 426, 654 |
| 3 | 449, 497, 213, 327 |
| 71 | 449, 497, 71, 109 |
| 449, 7, 1, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 449 x 7 x 1 x 109 = 145942062
Therefore, the lowest common multiple of 449,497,426,654 is 145942062.
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.
449 x 497 x 426 x 654 = 62171318412
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.
449 : 1, 449
497 : 1, 7, 71, 497
426 : 1, 2, 3, 6, 71, 142, 213, 426
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,497,426,654, is 1.
Now, the common factors can be found like this.
449:449
497:7x 71
426:2x 3x 71
654:2x 3x 109
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 71 = 426
Therefore, the value for common factors is 426.
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 = 62171318412/(1x426)
LCM = 62171318412/426
LCM = 145942062
Thus, we can understand that the LCM of 449,497,426,654 is 145942062.
