Given numbers are 642,614,241,953

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

The LCM of 642,614,241,953 is 45267170262.

Find LCM of 642,614,241,953 with Prime Factorization

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

2 x 321 x 307 x 241 x 953 = 45267170262

Therefore, the lowest common multiple of 642,614,241,953 is 45267170262.

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.

642 x 614 x 241 x 953 = 90534340524

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

614 : 1, 2, 307, 614

241 : 1, 241

953 : 1, 953

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,614,241,953, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

614:2x 307

241:241

953:953

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

2 = 2

Therefore, the value for common factors is 2.

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 = 90534340524/(1x2)

LCM = 90534340524/2

LCM = 45267170262

Thus, we can understand that the LCM of 642,614,241,953 is 45267170262.
