Given numbers are 578,847,306,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,847,306,946 is 189462042.
Find LCM of 578,847,306,946 with Prime Factorization
2 | 578, 847, 306, 946 |
11 | 289, 847, 153, 473 |
17 | 289, 77, 153, 43 |
17, 77, 9, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 17 x 77 x 9 x 43 = 189462042
Therefore, the lowest common multiple of 578,847,306,946 is 189462042.
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.
578 x 847 x 306 x 946 = 141717607416
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.
578 : 1, 2, 17, 34, 289, 578
847 : 1, 7, 11, 77, 121, 847
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,847,306,946, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
847:7x 11x 11
306:2x 3x 3x 17
946:2x 11x 43
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 141717607416/(1x748)
LCM = 141717607416/748
LCM = 189462042
Thus, we can understand that the LCM of 578,847,306,946 is 189462042.
