Given numbers are 642,777,775,219

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

The LCM of 642,777,775,219 is 9407177850.

Find LCM of 642,777,775,219 with Prime Factorization

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

3 x 214 x 259 x 775 x 73 = 9407177850

Therefore, the lowest common multiple of 642,777,775,219 is 9407177850.

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.

642 x 777 x 775 x 219 = 84664600650

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

777 : 1, 3, 7, 21, 37, 111, 259, 777

775 : 1, 5, 25, 31, 155, 775

219 : 1, 3, 73, 219

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,777,775,219, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

777:3x 7x 37

775:5x 5x 31

219:3x 73

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 84664600650/(1x9)

LCM = 84664600650/9

LCM = 9407177850

Thus, we can understand that the LCM of 642,777,775,219 is 9407177850.
