Given numbers are 245,206,678,638

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

The LCM of 245,206,678,638 is 5457876270.

Find LCM of 245,206,678,638 with Prime Factorization

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

2 x 245 x 103 x 339 x 319 = 5457876270

Therefore, the lowest common multiple of 245,206,678,638 is 5457876270.

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.

245 x 206 x 678 x 638 = 21831505080

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.

245 : 1, 5, 7, 35, 49, 245

206 : 1, 2, 103, 206

678 : 1, 2, 3, 6, 113, 226, 339, 678

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,206,678,638, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

206:2x 103

678:2x 3x 113

638:2x 11x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 21831505080/(1x4)

LCM = 21831505080/4

LCM = 5457876270

Thus, we can understand that the LCM of 245,206,678,638 is 5457876270.
