Given numbers are 207,283,989,391

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

The LCM of 207,283,989,391 is 42822711.

Find LCM of 207,283,989,391 with Prime Factorization

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

23 x 9 x 283 x 43 x 17 = 42822711

Therefore, the lowest common multiple of 207,283,989,391 is 42822711.

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.

207 x 283 x 989 x 391 = 22653214119

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.

207 : 1, 3, 9, 23, 69, 207

283 : 1, 283

989 : 1, 23, 43, 989

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,283,989,391, is 1.

Now, the common factors can be found like this.

207:3x 3x 23

283:283

989:23x 43

391:17x 23

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

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 22653214119/(1x529)

LCM = 22653214119/529

LCM = 42822711

Thus, we can understand that the LCM of 207,283,989,391 is 42822711.
