Given numbers are 390,618,279,862

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

The LCM of 390,618,279,862 is 1610134110.

Find LCM of 390,618,279,862 with Prime Factorization

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

2 x 3 x 65 x 103 x 93 x 431 = 1610134110

Therefore, the lowest common multiple of 390,618,279,862 is 1610134110.

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.

390 x 618 x 279 x 862 = 57964827960

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

618 : 1, 2, 3, 6, 103, 206, 309, 618

279 : 1, 3, 9, 31, 93, 279

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,618,279,862, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

618:2x 3x 103

279:3x 3x 31

862:2x 431

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 57964827960/(1x36)

LCM = 57964827960/36

LCM = 1610134110

Thus, we can understand that the LCM of 390,618,279,862 is 1610134110.
