Given numbers are 668,201,128,279,720

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

The LCM of 668,201,128,279,720 is 1997907840.

Find LCM of 668,201,128,279,720 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 3 x 167 x 67 x 8 x 31 x 5 = 1997907840

Therefore, the lowest common multiple of 668,201,128,279,720 is 1997907840.

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 201 x 128 x 279 x 720 = 3452384747520

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

201 : 1, 3, 67, 201

128 : 1, 2, 4, 8, 16, 32, 64, 128

279 : 1, 3, 9, 31, 93, 279

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,201,128,279,720, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

201:3x 67

128:2x 2x 2x 2x 2x 2x 2

279:3x 3x 31

720:2x 2x 2x 2x 3x 3x 5

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 2x 2x 2x 3x 3x 3 = 1728

Therefore, the value for common factors is 1728.

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 = 3452384747520/(1x1728)

LCM = 3452384747520/1728

LCM = 1997907840

Thus, we can understand that the LCM of 668,201,128,279,720 is 1997907840.
