Given numbers are 140,243,643,932

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

The LCM of 140,243,643,932 is 5096842380.

Find LCM of 140,243,643,932 with Prime Factorization

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

2 x 2 x 35 x 243 x 643 x 233 = 5096842380

Therefore, the lowest common multiple of 140,243,643,932 is 5096842380.

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.

140 x 243 x 643 x 932 = 20387369520

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.

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

243 : 1, 3, 9, 27, 81, 243

643 : 1, 643

932 : 1, 2, 4, 233, 466, 932

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,243,643,932, is 1.

Now, the common factors can be found like this.

140:2x 2x 5x 7

243:3x 3x 3x 3x 3

643:643

932:2x 2x 233

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 20387369520/(1x4)

LCM = 20387369520/4

LCM = 5096842380

Thus, we can understand that the LCM of 140,243,643,932 is 5096842380.
