Given numbers are 644,657,286,802

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

The LCM of 644,657,286,802 is 24262282044.

Find LCM of 644,657,286,802 with Prime Factorization

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

2 x 322 x 657 x 143 x 401 = 24262282044

Therefore, the lowest common multiple of 644,657,286,802 is 24262282044.

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.

644 x 657 x 286 x 802 = 97049128176

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

657 : 1, 3, 9, 73, 219, 657

286 : 1, 2, 11, 13, 22, 26, 143, 286

802 : 1, 2, 401, 802

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,657,286,802, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

657:3x 3x 73

286:2x 11x 13

802:2x 401

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 = 97049128176/(1x4)

LCM = 97049128176/4

LCM = 24262282044

Thus, we can understand that the LCM of 644,657,286,802 is 24262282044.
