Given numbers are 857,222,707,638

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

The LCM of 857,222,707,638 is 42908555382.

Find LCM of 857,222,707,638 with Prime Factorization

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

2 x 857 x 111 x 707 x 319 = 42908555382

Therefore, the lowest common multiple of 857,222,707,638 is 42908555382.

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.

857 x 222 x 707 x 638 = 85817110764

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.

857 : 1, 857

222 : 1, 2, 3, 6, 37, 74, 111, 222

707 : 1, 7, 101, 707

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 857,222,707,638, is 1.

Now, the common factors can be found like this.

857:857

222:2x 3x 37

707:7x 101

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 85817110764/(1x2)

LCM = 85817110764/2

LCM = 42908555382

Thus, we can understand that the LCM of 857,222,707,638 is 42908555382.
