Calculate the LCM of 669,668,442,848

Given numbers are 669,668,442,848

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

The LCM of 669,668,442,848 is 20937783984.

Find LCM of 669,668,442,848 with Prime Factorization


2 669, 668, 442, 848
2 669, 334, 221, 424
669, 167, 221, 212

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

2 x 2 x 669 x 167 x 221 x 212 = 20937783984

Therefore, the lowest common multiple of 669,668,442,848 is 20937783984.

LCM Formula to Find Lowest Common Multiple of 669,668,442,848

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.

669 x 668 x 442 x 848 = 167502271872

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.

669 : 1, 3, 223, 669

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

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

848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,668,442,848, is 1.

Now, the common factors can be found like this.

669:3x 223

668:2x 2x 167

442:2x 13x 17

848:2x 2x 2x 2x 53

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 2 = 8

Therefore, the value for common factors is 8.

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 = 167502271872/(1x8)

LCM = 167502271872/8

LCM = 20937783984

Thus, we can understand that the LCM of 669,668,442,848 is 20937783984.
