Given numbers are 161,494,622,771

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

The LCM of 161,494,622,771 is 19070742054.

Find LCM of 161,494,622,771 with Prime Factorization

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

2 x 161 x 247 x 311 x 771 = 19070742054

Therefore, the lowest common multiple of 161,494,622,771 is 19070742054.

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.

161 x 494 x 622 x 771 = 38141484108

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.

161 : 1, 7, 23, 161

494 : 1, 2, 13, 19, 26, 38, 247, 494

622 : 1, 2, 311, 622

771 : 1, 3, 257, 771

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,494,622,771, is 1.

Now, the common factors can be found like this.

161:7x 23

494:2x 13x 19

622:2x 311

771:3x 257

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 = 38141484108/(1x2)

LCM = 38141484108/2

LCM = 19070742054

Thus, we can understand that the LCM of 161,494,622,771 is 19070742054.
