Given numbers are 194,721,563,198,430

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

The LCM of 194,721,563,198,430 is 1676173784670.

Find LCM of 194,721,563,198,430 with Prime Factorization

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

2 x 97 x 721 x 563 x 99 x 215 = 1676173784670

Therefore, the lowest common multiple of 194,721,563,198,430 is 1676173784670.

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.

194 x 721 x 563 x 198 x 430 = 6704695138680

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.

194 : 1, 2, 97, 194

721 : 1, 7, 103, 721

563 : 1, 563

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,721,563,198,430, is 1.

Now, the common factors can be found like this.

194:2x 97

721:7x 103

563:563

198:2x 3x 3x 11

430:2x 5x 43

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 = 6704695138680/(1x4)

LCM = 6704695138680/4

LCM = 1676173784670

Thus, we can understand that the LCM of 194,721,563,198,430 is 1676173784670.
