Given numbers are 644,471,598,266

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

The LCM of 644,471,598,266 is 74921028.

Find LCM of 644,471,598,266 with Prime Factorization

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

2 x 7 x 23 x 2 x 471 x 13 x 19 = 74921028

Therefore, the lowest common multiple of 644,471,598,266 is 74921028.

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 471 x 598 x 266 = 48249142032

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

471 : 1, 3, 157, 471

598 : 1, 2, 13, 23, 26, 46, 299, 598

266 : 1, 2, 7, 14, 19, 38, 133, 266

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,471,598,266, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

471:3x 157

598:2x 13x 23

266:2x 7x 19

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

2x 2x 7x 23 = 644

Therefore, the value for common factors is 644.

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 = 48249142032/(1x644)

LCM = 48249142032/644

LCM = 74921028

Thus, we can understand that the LCM of 644,471,598,266 is 74921028.
