Given numbers are 565,840,686,574
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 565,840,686,574 is 190694280.
Find LCM of 565,840,686,574 with Prime Factorization
2 | 565, 840, 686, 574 |
5 | 565, 420, 343, 287 |
7 | 113, 84, 343, 287 |
113, 12, 49, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 113 x 12 x 49 x 41 = 190694280
Therefore, the lowest common multiple of 565,840,686,574 is 190694280.
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.
565 x 840 x 686 x 574 = 186880394400
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.
565 : 1, 5, 113, 565
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
686 : 1, 2, 7, 14, 49, 98, 343, 686
574 : 1, 2, 7, 14, 41, 82, 287, 574
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 565,840,686,574, is 1.
Now, the common factors can be found like this.
565:5x 113
840:2x 2x 2x 3x 5x 7
686:2x 7x 7x 7
574:2x 7x 41
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 5x 7x 7 = 980
Therefore, the value for common factors is 980.
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 = 186880394400/(1x980)
LCM = 186880394400/980
LCM = 190694280
Thus, we can understand that the LCM of 565,840,686,574 is 190694280.
