Given numbers are 642,577,305,290

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

The LCM of 642,577,305,290 is 3276488730.

Find LCM of 642,577,305,290 with Prime Factorization

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

2 x 5 x 321 x 577 x 61 x 29 = 3276488730

Therefore, the lowest common multiple of 642,577,305,290 is 3276488730.

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 577 x 305 x 290 = 32764887300

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

577 : 1, 577

305 : 1, 5, 61, 305

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,577,305,290, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

577:577

305:5x 61

290:2x 5x 29

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 32764887300/(1x10)

LCM = 32764887300/10

LCM = 3276488730

Thus, we can understand that the LCM of 642,577,305,290 is 3276488730.
