Given numbers are 988,121,161,682

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

The LCM of 988,121,161,682 is 596664068.

Find LCM of 988,121,161,682 with Prime Factorization

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

2 x 11 x 494 x 11 x 161 x 31 = 596664068

Therefore, the lowest common multiple of 988,121,161,682 is 596664068.

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 121 x 161 x 682 = 13126609496

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

121 : 1, 11, 121

161 : 1, 7, 23, 161

682 : 1, 2, 11, 22, 31, 62, 341, 682

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,121,161,682, is 1.

Now, the common factors can be found like this.

988:2x 2x 13x 19

121:11x 11

161:7x 23

682:2x 11x 31

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 13126609496/(1x22)

LCM = 13126609496/22

LCM = 596664068

Thus, we can understand that the LCM of 988,121,161,682 is 596664068.

Here are some samples of LCM of two or more Numbers calculations.
