Given numbers are 643,611,403,359

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

The LCM of 643,611,403,359 is 4372283617.

Find LCM of 643,611,403,359 with Prime Factorization

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

13 x 643 x 47 x 31 x 359 = 4372283617

Therefore, the lowest common multiple of 643,611,403,359 is 4372283617.

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.

643 x 611 x 403 x 359 = 56839687021

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.

643 : 1, 643

611 : 1, 13, 47, 611

403 : 1, 13, 31, 403

359 : 1, 359

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,611,403,359, is 1.

Now, the common factors can be found like this.

643:643

611:13x 47

403:13x 31

359:359

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

13 = 13

Therefore, the value for common factors is 13.

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 = 56839687021/(1x13)

LCM = 56839687021/13

LCM = 4372283617

Thus, we can understand that the LCM of 643,611,403,359 is 4372283617.
