Given numbers are 641,457,252,208

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

The LCM of 641,457,252,208 is 3838646448.

Find LCM of 641,457,252,208 with Prime Factorization

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

2 x 2 x 641 x 457 x 63 x 52 = 3838646448

Therefore, the lowest common multiple of 641,457,252,208 is 3838646448.

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.

641 x 457 x 252 x 208 = 15354585792

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.

641 : 1, 641

457 : 1, 457

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,457,252,208, is 1.

Now, the common factors can be found like this.

641:641

457:457

252:2x 2x 3x 3x 7

208:2x 2x 2x 2x 13

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 = 15354585792/(1x4)

LCM = 15354585792/4

LCM = 3838646448

Thus, we can understand that the LCM of 641,457,252,208 is 3838646448.
