Given numbers are 505,721,208,247

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

The LCM of 505,721,208,247 is 1438942960.

Find LCM of 505,721,208,247 with Prime Factorization

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

13 x 505 x 721 x 16 x 19 = 1438942960

Therefore, the lowest common multiple of 505,721,208,247 is 1438942960.

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.

505 x 721 x 208 x 247 = 18706258480

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.

505 : 1, 5, 101, 505

721 : 1, 7, 103, 721

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,721,208,247, is 1.

Now, the common factors can be found like this.

505:5x 101

721:7x 103

208:2x 2x 2x 2x 13

247:13x 19

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

13 = 13

Therefore, the value for common factors is 13.

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 = 18706258480/(1x13)

LCM = 18706258480/13

LCM = 1438942960

Thus, we can understand that the LCM of 505,721,208,247 is 1438942960.
