Given numbers are 621,511,924,770

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

The LCM of 621,511,924,770 is 69812820.

Find LCM of 621,511,924,770 with Prime Factorization

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

2 x 3 x 7 x 11 x 207 x 73 x 2 x 5 = 69812820

Therefore, the lowest common multiple of 621,511,924,770 is 69812820.

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.

621 x 511 x 924 x 770 = 225774659880

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

511 : 1, 7, 73, 511

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,511,924,770, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

511:7x 73

924:2x 2x 3x 7x 11

770:2x 5x 7x 11

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

2x 3x 7x 7x 11 = 3234

Therefore, the value for common factors is 3234.

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 = 225774659880/(1x3234)

LCM = 225774659880/3234

LCM = 69812820

Thus, we can understand that the LCM of 621,511,924,770 is 69812820.
