Given numbers are 668,534,374,641

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

The LCM of 668,534,374,641 is 21378998652.

Find LCM of 668,534,374,641 with Prime Factorization

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

2 x 334 x 267 x 187 x 641 = 21378998652

Therefore, the lowest common multiple of 668,534,374,641 is 21378998652.

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.

668 x 534 x 374 x 641 = 85515994608

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.

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

534 : 1, 2, 3, 6, 89, 178, 267, 534

374 : 1, 2, 11, 17, 22, 34, 187, 374

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,534,374,641, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

534:2x 3x 89

374:2x 11x 17

641:641

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 85515994608/(1x4)

LCM = 85515994608/4

LCM = 21378998652

Thus, we can understand that the LCM of 668,534,374,641 is 21378998652.
