Given numbers are 638,760,208,598,760

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

The LCM of 638,760,208,598,760 is 144979120.

Find LCM of 638,760,208,598,760 with Prime Factorization

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

2 x 2 x 2 x 5 x 13 x 19 x 319 x 1 x 2 x 23 x 1 = 144979120

Therefore, the lowest common multiple of 638,760,208,598,760 is 144979120.

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.

638 x 760 x 208 x 598 x 760 = 45836598579200

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

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

598 : 1, 2, 13, 23, 26, 46, 299, 598

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,760,208,598,760, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

760:2x 2x 2x 5x 19

208:2x 2x 2x 2x 13

598:2x 13x 23

760:2x 2x 2x 5x 19

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

2x 2x 2x 2x 2x 2x 2x 5x 13x 19 = 158080

Therefore, the value for common factors is 158080.

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 = 45836598579200/(2x158080)

LCM = 45836598579200/316160

LCM = 144979120

Thus, we can understand that the LCM of 638,760,208,598,760 is 144979120.
