Given numbers are 561,947,686,524
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,947,686,524 is 95485680444.
Find LCM of 561,947,686,524 with Prime Factorization
2 | 561, 947, 686, 524 |
561, 947, 343, 262 |
Multiply the prime numbers at the bottom and the left side.
2 x 561 x 947 x 343 x 262 = 95485680444
Therefore, the lowest common multiple of 561,947,686,524 is 95485680444.
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.
561 x 947 x 686 x 524 = 190971360888
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
947 : 1, 947
686 : 1, 2, 7, 14, 49, 98, 343, 686
524 : 1, 2, 4, 131, 262, 524
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,947,686,524, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
947:947
686:2x 7x 7x 7
524:2x 2x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 190971360888/(1x2)
LCM = 190971360888/2
LCM = 95485680444
Thus, we can understand that the LCM of 561,947,686,524 is 95485680444.
