Given numbers are 709,691,646,874

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

The LCM of 709,691,646,874 is 7279216502.

Find LCM of 709,691,646,874 with Prime Factorization

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

2 x 19 x 709 x 691 x 17 x 23 = 7279216502

Therefore, the lowest common multiple of 709,691,646,874 is 7279216502.

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.

709 x 691 x 646 x 874 = 276610227076

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.

709 : 1, 709

691 : 1, 691

646 : 1, 2, 17, 19, 34, 38, 323, 646

874 : 1, 2, 19, 23, 38, 46, 437, 874

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,691,646,874, is 1.

Now, the common factors can be found like this.

709:709

691:691

646:2x 17x 19

874:2x 19x 23

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 276610227076/(1x38)

LCM = 276610227076/38

LCM = 7279216502

Thus, we can understand that the LCM of 709,691,646,874 is 7279216502.
