Given numbers are 988,128,248,676

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 988,128,248,676 is 12741248.

Find LCM of 988,128,248,676 with Prime Factorization

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

2 x 2 x 2 x 13 x 19 x 16 x 31 x 13 = 12741248

Therefore, the lowest common multiple of 988,128,248,676 is 12741248.

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.

988 x 128 x 248 x 676 = 21201436672

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.

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

128 : 1, 2, 4, 8, 16, 32, 64, 128

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

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,128,248,676, is 4.

Now, the common factors can be found like this.

988:2x 2x 13x 19

128:2x 2x 2x 2x 2x 2x 2

248:2x 2x 2x 31

676:2x 2x 13x 13

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 2x 2x 2x 13 = 416

Therefore, the value for common factors is 416.

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 = 21201436672/(4x416)

LCM = 21201436672/1664

LCM = 12741248

Thus, we can understand that the LCM of 988,128,248,676 is 12741248.
