Given numbers are 395,994,281,138

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

The LCM of 395,994,281,138 is 7612703070.

Find LCM of 395,994,281,138 with Prime Factorization

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

2 x 395 x 497 x 281 x 69 = 7612703070

Therefore, the lowest common multiple of 395,994,281,138 is 7612703070.

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.

395 x 994 x 281 x 138 = 15225406140

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.

395 : 1, 5, 79, 395

994 : 1, 2, 7, 14, 71, 142, 497, 994

281 : 1, 281

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,994,281,138, is 1.

Now, the common factors can be found like this.

395:5x 79

994:2x 7x 71

281:281

138:2x 3x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 15225406140/(1x2)

LCM = 15225406140/2

LCM = 7612703070

Thus, we can understand that the LCM of 395,994,281,138 is 7612703070.
