Calculate the LCM of 172,668,247,798

Given numbers are 172,668,247,798

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

The LCM of 172,668,247,798 is 148991388.

Find LCM of 172,668,247,798 with Prime Factorization


2 172, 668, 247, 798
2 86, 334, 247, 399
19 43, 167, 247, 399
43, 167, 13, 21

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

2 x 2 x 19 x 43 x 167 x 13 x 21 = 148991388

Therefore, the lowest common multiple of 172,668,247,798 is 148991388.

LCM Formula to Find Lowest Common Multiple of 172,668,247,798

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.

172 x 668 x 247 x 798 = 22646690976

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.

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

668 : 1, 2, 4, 167, 334, 668

247 : 1, 13, 19, 247

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,668,247,798, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

668:2x 2x 167

247:13x 19

798:2x 3x 7x 19

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 19 = 152

Therefore, the value for common factors is 152.

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 = 22646690976/(1x152)

LCM = 22646690976/152

LCM = 148991388

Thus, we can understand that the LCM of 172,668,247,798 is 148991388.
