Given numbers are 672,812,717,861,654

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

The LCM of 672,812,717,861,654 is 20814957408.

Find LCM of 672,812,717,861,654 with Prime Factorization

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

2 x 2 x 3 x 7 x 8 x 29 x 239 x 41 x 109 = 20814957408

Therefore, the lowest common multiple of 672,812,717,861,654 is 20814957408.

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.

672 x 812 x 717 x 861 x 654 = 220305509206272

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

717 : 1, 3, 239, 717

861 : 1, 3, 7, 21, 41, 123, 287, 861

654 : 1, 2, 3, 6, 109, 218, 327, 654

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,812,717,861,654, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

812:2x 2x 7x 29

717:3x 239

861:3x 7x 41

654:2x 3x 109

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 3x 3x 3x 7x 7 = 10584

Therefore, the value for common factors is 10584.

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 = 220305509206272/(1x10584)

LCM = 220305509206272/10584

LCM = 20814957408

Thus, we can understand that the LCM of 672,812,717,861,654 is 20814957408.
