Given numbers are 516,622,317,421

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

The LCM of 516,622,317,421 is 21416645532.

Find LCM of 516,622,317,421 with Prime Factorization

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

2 x 258 x 311 x 317 x 421 = 21416645532

Therefore, the lowest common multiple of 516,622,317,421 is 21416645532.

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.

516 x 622 x 317 x 421 = 42833291064

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.

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

622 : 1, 2, 311, 622

317 : 1, 317

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,622,317,421, is 1.

Now, the common factors can be found like this.

516:2x 2x 3x 43

622:2x 311

317:317

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 42833291064/(1x2)

LCM = 42833291064/2

LCM = 21416645532

Thus, we can understand that the LCM of 516,622,317,421 is 21416645532.
