Given numbers are 974,174,221,808

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

The LCM of 974,174,221,808 is 7565747592.

Find LCM of 974,174,221,808 with Prime Factorization

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

2 x 487 x 87 x 221 x 404 = 7565747592

Therefore, the lowest common multiple of 974,174,221,808 is 7565747592.

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.

974 x 174 x 221 x 808 = 30262990368

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.

974 : 1, 2, 487, 974

174 : 1, 2, 3, 6, 29, 58, 87, 174

221 : 1, 13, 17, 221

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,174,221,808, is 1.

Now, the common factors can be found like this.

974:2x 487

174:2x 3x 29

221:13x 17

808:2x 2x 2x 101

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 30262990368/(1x4)

LCM = 30262990368/4

LCM = 7565747592

Thus, we can understand that the LCM of 974,174,221,808 is 7565747592.
