Given numbers are 442,952,946,385,691

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

The LCM of 442,952,946,385,691 is 20225044840.

Find LCM of 442,952,946,385,691 with Prime Factorization

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

2 x 7 x 11 x 17 x 13 x 4 x 43 x 5 x 691 = 20225044840

Therefore, the lowest common multiple of 442,952,946,385,691 is 20225044840.

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.

442 x 952 x 946 x 385 x 691 = 105898334782240

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952

946 : 1, 2, 11, 22, 43, 86, 473, 946

385 : 1, 5, 7, 11, 35, 55, 77, 385

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,952,946,385,691, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

952:2x 2x 2x 7x 17

946:2x 11x 43

385:5x 7x 11

691:691

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

2x 2x 7x 11x 17 = 5236

Therefore, the value for common factors is 5236.

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 = 105898334782240/(1x5236)

LCM = 105898334782240/5236

LCM = 20225044840

Thus, we can understand that the LCM of 442,952,946,385,691 is 20225044840.
