Given numbers are 523,548,574,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 523,548,574,861 is 246766044.
Find LCM of 523,548,574,861 with Prime Factorization
| 2 | 523, 548, 574, 861 |
| 7 | 523, 274, 287, 861 |
| 41 | 523, 274, 41, 123 |
| 523, 274, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 523 x 274 x 1 x 3 = 246766044
Therefore, the lowest common multiple of 523,548,574,861 is 246766044.
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.
523 x 548 x 574 x 861 = 141643709256
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.
523 : 1, 523
548 : 1, 2, 4, 137, 274, 548
574 : 1, 2, 7, 14, 41, 82, 287, 574
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,548,574,861, is 1.
Now, the common factors can be found like this.
523:523
548:2x 2x 137
574:2x 7x 41
861:3x 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 7x 41 = 574
Therefore, the value for common factors is 574.
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 = 141643709256/(1x574)
LCM = 141643709256/574
LCM = 246766044
Thus, we can understand that the LCM of 523,548,574,861 is 246766044.
