Given numbers are 142,242,198,451

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

The LCM of 142,242,198,451 is 6340158.

Find LCM of 142,242,198,451 with Prime Factorization

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

2 x 11 x 71 x 11 x 9 x 41 = 6340158

Therefore, the lowest common multiple of 142,242,198,451 is 6340158.

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.

142 x 242 x 198 x 451 = 3068636472

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.

142 : 1, 2, 71, 142

242 : 1, 2, 11, 22, 121, 242

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

451 : 1, 11, 41, 451

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,242,198,451, is 1.

Now, the common factors can be found like this.

142:2x 71

242:2x 11x 11

198:2x 3x 3x 11

451:11x 41

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 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 3068636472/(1x484)

LCM = 3068636472/484

LCM = 6340158

Thus, we can understand that the LCM of 142,242,198,451 is 6340158.
