Given numbers are 407,221,965,965

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

The LCM of 407,221,965,965 is 86798855.

Find LCM of 407,221,965,965 with Prime Factorization

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

5 x 193 x 407 x 221 x 1 x 1 = 86798855

Therefore, the lowest common multiple of 407,221,965,965 is 86798855.

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.

407 x 221 x 965 x 965 = 83760895075

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.

407 : 1, 11, 37, 407

221 : 1, 13, 17, 221

965 : 1, 5, 193, 965

965 : 1, 5, 193, 965

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,221,965,965, is 1.

Now, the common factors can be found like this.

407:11x 37

221:13x 17

965:5x 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.

5x 193 = 965

Therefore, the value for common factors is 965.

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 = 83760895075/(1x965)

LCM = 83760895075/965

LCM = 86798855

Thus, we can understand that the LCM of 407,221,965,965 is 86798855.
