Given numbers are 681,721,473,824

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

The LCM of 681,721,473,824 is 1857947784.

Find LCM of 681,721,473,824 with Prime Factorization

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

103 x 681 x 7 x 473 x 8 = 1857947784

Therefore, the lowest common multiple of 681,721,473,824 is 1857947784.

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.

681 x 721 x 473 x 824 = 191368621752

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.

681 : 1, 3, 227, 681

721 : 1, 7, 103, 721

473 : 1, 11, 43, 473

824 : 1, 2, 4, 8, 103, 206, 412, 824

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,721,473,824, is 1.

Now, the common factors can be found like this.

681:3x 227

721:7x 103

473:11x 43

824:2x 2x 2x 103

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

103 = 103

Therefore, the value for common factors is 103.

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 = 191368621752/(1x103)

LCM = 191368621752/103

LCM = 1857947784

Thus, we can understand that the LCM of 681,721,473,824 is 1857947784.
