Given numbers are 354,643,731,124,161

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

The LCM of 354,643,731,124,161 is 1660921769724.

Find LCM of 354,643,731,124,161 with Prime Factorization

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

2 x 177 x 643 x 731 x 62 x 161 = 1660921769724

Therefore, the lowest common multiple of 354,643,731,124,161 is 1660921769724.

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.

354 x 643 x 731 x 124 x 161 = 3321843539448

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.

354 : 1, 2, 3, 6, 59, 118, 177, 354

643 : 1, 643

731 : 1, 17, 43, 731

124 : 1, 2, 4, 31, 62, 124

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,643,731,124,161, is 1.

Now, the common factors can be found like this.

354:2x 3x 59

643:643

731:17x 43

124:2x 2x 31

161:7x 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 = 3321843539448/(1x2)

LCM = 3321843539448/2

LCM = 1660921769724

Thus, we can understand that the LCM of 354,643,731,124,161 is 1660921769724.
