Given numbers are 639,183,497,471

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

The LCM of 639,183,497,471 is 42837921.

Find LCM of 639,183,497,471 with Prime Factorization

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

3 x 71 x 3 x 61 x 7 x 157 = 42837921

Therefore, the lowest common multiple of 639,183,497,471 is 42837921.

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.

639 x 183 x 497 x 471 = 27373431519

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.

639 : 1, 3, 9, 71, 213, 639

183 : 1, 3, 61, 183

497 : 1, 7, 71, 497

471 : 1, 3, 157, 471

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,183,497,471, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

183:3x 61

497:7x 71

471:3x 157

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

3x 3x 71 = 639

Therefore, the value for common factors is 639.

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 = 27373431519/(1x639)

LCM = 27373431519/639

LCM = 42837921

Thus, we can understand that the LCM of 639,183,497,471 is 42837921.
