Given numbers are 730,694,657,641

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

The LCM of 730,694,657,641 is 1461345390.

Find LCM of 730,694,657,641 with Prime Factorization

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

2 x 73 x 5 x 347 x 9 x 641 = 1461345390

Therefore, the lowest common multiple of 730,694,657,641 is 1461345390.

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.

730 x 694 x 657 x 641 = 213356426940

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.

730 : 1, 2, 5, 10, 73, 146, 365, 730

694 : 1, 2, 347, 694

657 : 1, 3, 9, 73, 219, 657

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,694,657,641, is 1.

Now, the common factors can be found like this.

730:2x 5x 73

694:2x 347

657:3x 3x 73

641:641

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

2x 73 = 146

Therefore, the value for common factors is 146.

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 = 213356426940/(1x146)

LCM = 213356426940/146

LCM = 1461345390

Thus, we can understand that the LCM of 730,694,657,641 is 1461345390.
