Given numbers are 871,856,642,253

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

The LCM of 871,856,642,253 is 565892184.

Find LCM of 871,856,642,253 with Prime Factorization

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

2 x 107 x 871 x 4 x 3 x 253 = 565892184

Therefore, the lowest common multiple of 871,856,642,253 is 565892184.

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.

871 x 856 x 642 x 253 = 121100927376

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.

871 : 1, 13, 67, 871

856 : 1, 2, 4, 8, 107, 214, 428, 856

642 : 1, 2, 3, 6, 107, 214, 321, 642

253 : 1, 11, 23, 253

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,856,642,253, is 1.

Now, the common factors can be found like this.

871:13x 67

856:2x 2x 2x 107

642:2x 3x 107

253:11x 23

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 121100927376/(1x214)

LCM = 121100927376/214

LCM = 565892184

Thus, we can understand that the LCM of 871,856,642,253 is 565892184.
