Given numbers are 238,134,865,921

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

The LCM of 238,134,865,921 is 12703620090.

Find LCM of 238,134,865,921 with Prime Factorization

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

2 x 119 x 67 x 865 x 921 = 12703620090

Therefore, the lowest common multiple of 238,134,865,921 is 12703620090.

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.

238 x 134 x 865 x 921 = 25407240180

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.

238 : 1, 2, 7, 14, 17, 34, 119, 238

134 : 1, 2, 67, 134

865 : 1, 5, 173, 865

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,134,865,921, is 1.

Now, the common factors can be found like this.

238:2x 7x 17

134:2x 67

865:5x 173

921:3x 307

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

2 = 2

Therefore, the value for common factors is 2.

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 = 25407240180/(1x2)

LCM = 25407240180/2

LCM = 12703620090

Thus, we can understand that the LCM of 238,134,865,921 is 12703620090.
