Given numbers are 639,823,193,965

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

The LCM of 639,823,193,965 is 507490605.

Find LCM of 639,823,193,965 with Prime Factorization

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

193 x 639 x 823 x 1 x 5 = 507490605

Therefore, the lowest common multiple of 639,823,193,965 is 507490605.

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 823 x 193 x 965 = 97945686765

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

823 : 1, 823

193 : 1, 193

965 : 1, 5, 193, 965

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,823,193,965, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

823:823

193:193

965:5x 193

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

193 = 193

Therefore, the value for common factors is 193.

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 = 97945686765/(1x193)

LCM = 97945686765/193

LCM = 507490605

Thus, we can understand that the LCM of 639,823,193,965 is 507490605.
