Given numbers are 644,643,534,962

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

The LCM of 644,643,534,962 is 53180593284.

Find LCM of 644,643,534,962 with Prime Factorization

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

2 x 322 x 643 x 267 x 481 = 53180593284

Therefore, the lowest common multiple of 644,643,534,962 is 53180593284.

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 643 x 534 x 962 = 212722373136

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

643 : 1, 643

534 : 1, 2, 3, 6, 89, 178, 267, 534

962 : 1, 2, 13, 26, 37, 74, 481, 962

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,643,534,962, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

643:643

534:2x 3x 89

962:2x 13x 37

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 = 212722373136/(1x4)

LCM = 212722373136/4

LCM = 53180593284

Thus, we can understand that the LCM of 644,643,534,962 is 53180593284.
