Given numbers are 948,698,990,988

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

The LCM of 948,698,990,988 is 13483873260.

Find LCM of 948,698,990,988 with Prime Factorization

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

2 x 2 x 3 x 79 x 349 x 165 x 247 = 13483873260

Therefore, the lowest common multiple of 948,698,990,988 is 13483873260.

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.

948 x 698 x 990 x 988 = 647225916480

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.

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

698 : 1, 2, 349, 698

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 948,698,990,988, is 2.

Now, the common factors can be found like this.

948:2x 2x 3x 79

698:2x 349

990:2x 3x 3x 5x 11

988:2x 2x 13x 19

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 3 = 24

Therefore, the value for common factors is 24.

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 = 647225916480/(2x24)

LCM = 647225916480/48

LCM = 13483873260

Thus, we can understand that the LCM of 948,698,990,988 is 13483873260.
