Given numbers are 641,139,542,695

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

The LCM of 641,139,542,695 is 241458290.

Find LCM of 641,139,542,695 with Prime Factorization

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

139 x 641 x 1 x 542 x 5 = 241458290

Therefore, the lowest common multiple of 641,139,542,695 is 241458290.

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.

641 x 139 x 542 x 695 = 33562702310

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.

641 : 1, 641

139 : 1, 139

542 : 1, 2, 271, 542

695 : 1, 5, 139, 695

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,139,542,695, is 1.

Now, the common factors can be found like this.

641:641

139:139

542:2x 271

695:5x 139

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

139 = 139

Therefore, the value for common factors is 139.

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 = 33562702310/(1x139)

LCM = 33562702310/139

LCM = 241458290

Thus, we can understand that the LCM of 641,139,542,695 is 241458290.
