Find LCM of 546,858,491,428 with Prime Factorization
| 2 | 546, 858, 491, 428 |
| 3 | 273, 429, 491, 214 |
| 13 | 91, 143, 491, 214 |
| 7, 11, 491, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 7 x 11 x 491 x 214 = 631074444
Therefore, the lowest common multiple of 546,858,491,428 is 631074444.
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.
546 x 858 x 491 x 428 = 98447613264
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
491 : 1, 491
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,858,491,428, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
858:2x 3x 11x 13
491:491
428:2x 2x 107
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 98447613264/(1x156)
LCM = 98447613264/156
LCM = 631074444
Thus, we can understand that the LCM of 546,858,491,428 is 631074444.
