Given numbers are 664,685,942,581

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

The LCM of 664,685,942,581 is 1499607480.

Find LCM of 664,685,942,581 with Prime Factorization

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

2 x 83 x 4 x 685 x 471 x 7 = 1499607480

Therefore, the lowest common multiple of 664,685,942,581 is 1499607480.

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.

664 x 685 x 942 x 581 = 248934841680

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

685 : 1, 5, 137, 685

942 : 1, 2, 3, 6, 157, 314, 471, 942

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,685,942,581, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

685:5x 137

942:2x 3x 157

581:7x 83

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

2x 83 = 166

Therefore, the value for common factors is 166.

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 = 248934841680/(1x166)

LCM = 248934841680/166

LCM = 1499607480

Thus, we can understand that the LCM of 664,685,942,581 is 1499607480.
