Given numbers are 142,409,994,845

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

The LCM of 142,409,994,845 is 343531370.

Find LCM of 142,409,994,845 with Prime Factorization

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

2 x 71 x 1 x 409 x 7 x 845 = 343531370

Therefore, the lowest common multiple of 142,409,994,845 is 343531370.

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 409 x 994 x 845 = 48781454540

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

409 : 1, 409

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

845 : 1, 5, 13, 65, 169, 845

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,409,994,845, is 1.

Now, the common factors can be found like this.

142:2x 71

409:409

994:2x 7x 71

845:5x 13x 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 71 = 142

Therefore, the value for common factors is 142.

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 = 48781454540/(1x142)

LCM = 48781454540/142

LCM = 343531370

Thus, we can understand that the LCM of 142,409,994,845 is 343531370.
