Given numbers are 641,791,904,694

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

The LCM of 641,791,904,694 is 1407518056.

Find LCM of 641,791,904,694 with Prime Factorization

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

2 x 113 x 641 x 7 x 4 x 347 = 1407518056

Therefore, the lowest common multiple of 641,791,904,694 is 1407518056.

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 791 x 904 x 694 = 318099080656

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

791 : 1, 7, 113, 791

904 : 1, 2, 4, 8, 113, 226, 452, 904

694 : 1, 2, 347, 694

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,791,904,694, is 1.

Now, the common factors can be found like this.

641:641

791:7x 113

904:2x 2x 2x 113

694:2x 347

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

2x 113 = 226

Therefore, the value for common factors is 226.

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 = 318099080656/(1x226)

LCM = 318099080656/226

LCM = 1407518056

Thus, we can understand that the LCM of 641,791,904,694 is 1407518056.
