The LCM of 248,961,686,530 is 698800760.

Find LCM of 248,961,686,530 with Prime Factorization


2 248, 961, 686, 530
31 124, 961, 343, 265
4, 31, 343, 265

Multiply the prime numbers at the bottom and the left side.

2 x 31 x 4 x 31 x 343 x 265 = 698800760

Therefore, the lowest common multiple of 248,961,686,530 is 698800760.

LCM Formula to Find Lowest Common Multiple of 248,961,686,530

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.

248 x 961 x 686 x 530 = 86651294240

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.

248 : 1, 2, 4, 8, 31, 62, 124, 248

961 : 1, 31, 961

686 : 1, 2, 7, 14, 49, 98, 343, 686

530 : 1, 2, 5, 10, 53, 106, 265, 530

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,961,686,530, is 1.

Now, the common factors can be found like this.

248:2x 2x 2x 31

961:31x 31

686:2x 7x 7x 7

530:2x 5x 53

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 31 = 124

Therefore, the value for common factors is 124.

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 = 86651294240/(1x124)

LCM = 86651294240/124

LCM = 698800760

Thus, we can understand that the LCM of 248,961,686,530 is 698800760.
