Given numbers are 988,726,396,428

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

The LCM of 988,726,396,428 is 115124724.

Find LCM of 988,726,396,428 with Prime Factorization

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

2 x 2 x 3 x 11 x 247 x 11 x 3 x 107 = 115124724

Therefore, the lowest common multiple of 988,726,396,428 is 115124724.

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 726 x 396 x 428 = 121571708544

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

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

428 : 1, 2, 4, 107, 214, 428

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,726,396,428, is 2.

Now, the common factors can be found like this.

988:2x 2x 13x 19

726:2x 3x 11x 11

396:2x 2x 3x 3x 11

428:2x 2x 107

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 3x 11 = 528

Therefore, the value for common factors is 528.

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 = 121571708544/(2x528)

LCM = 121571708544/1056

LCM = 115124724

Thus, we can understand that the LCM of 988,726,396,428 is 115124724.
