Given numbers are 641,130,407,627

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

The LCM of 641,130,407,627 is 1933172670.

Find LCM of 641,130,407,627 with Prime Factorization

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

11 x 641 x 130 x 37 x 57 = 1933172670

Therefore, the lowest common multiple of 641,130,407,627 is 1933172670.

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 130 x 407 x 627 = 21264899370

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

130 : 1, 2, 5, 10, 13, 26, 65, 130

407 : 1, 11, 37, 407

627 : 1, 3, 11, 19, 33, 57, 209, 627

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,130,407,627, is 1.

Now, the common factors can be found like this.

641:641

130:2x 5x 13

407:11x 37

627:3x 11x 19

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

11 = 11

Therefore, the value for common factors is 11.

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 = 21264899370/(1x11)

LCM = 21264899370/11

LCM = 1933172670

Thus, we can understand that the LCM of 641,130,407,627 is 1933172670.
