Given numbers are 511,340,417,642

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

The LCM of 511,340,417,642 is 7752105060.

Find LCM of 511,340,417,642 with Prime Factorization

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

2 x 3 x 511 x 170 x 139 x 107 = 7752105060

Therefore, the lowest common multiple of 511,340,417,642 is 7752105060.

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.

511 x 340 x 417 x 642 = 46512630360

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.

511 : 1, 7, 73, 511

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

417 : 1, 3, 139, 417

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,340,417,642, is 1.

Now, the common factors can be found like this.

511:7x 73

340:2x 2x 5x 17

417:3x 139

642:2x 3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 46512630360/(1x6)

LCM = 46512630360/6

LCM = 7752105060

Thus, we can understand that the LCM of 511,340,417,642 is 7752105060.
