Calculate the LCM of 895,172,421,442

Given numbers are 895,172,421,442

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

The LCM of 895,172,421,442 is 14322731540.

Find LCM of 895,172,421,442 with Prime Factorization


2 895, 172, 421, 442
895, 86, 421, 221

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

2 x 895 x 86 x 421 x 221 = 14322731540

Therefore, the lowest common multiple of 895,172,421,442 is 14322731540.

LCM Formula to Find Lowest Common Multiple of 895,172,421,442

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.

895 x 172 x 421 x 442 = 28645463080

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.

895 : 1, 5, 179, 895

172 : 1, 2, 4, 43, 86, 172

421 : 1, 421

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 895,172,421,442, is 1.

Now, the common factors can be found like this.

895:5x 179

172:2x 2x 43

421:421

442:2x 13x 17

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 = 28645463080/(1x2)

LCM = 28645463080/2

LCM = 14322731540

Thus, we can understand that the LCM of 895,172,421,442 is 14322731540.
