Given numbers are 640,201,706,376

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

The LCM of 640,201,706,376 is 2134266240.

Find LCM of 640,201,706,376 with Prime Factorization

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

2 x 2 x 2 x 80 x 201 x 353 x 47 = 2134266240

Therefore, the lowest common multiple of 640,201,706,376 is 2134266240.

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.

640 x 201 x 706 x 376 = 34148259840

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

201 : 1, 3, 67, 201

706 : 1, 2, 353, 706

376 : 1, 2, 4, 8, 47, 94, 188, 376

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,201,706,376, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

201:3x 67

706:2x 353

376:2x 2x 2x 47

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 2 = 16

Therefore, the value for common factors is 16.

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 = 34148259840/(1x16)

LCM = 34148259840/16

LCM = 2134266240

Thus, we can understand that the LCM of 640,201,706,376 is 2134266240.
