Given numbers are 857,611,432,172

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

The LCM of 857,611,432,172 is 9726895152.

Find LCM of 857,611,432,172 with Prime Factorization

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

2 x 2 x 857 x 611 x 108 x 43 = 9726895152

Therefore, the lowest common multiple of 857,611,432,172 is 9726895152.

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 611 x 432 x 172 = 38907580608

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

611 : 1, 13, 47, 611

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,611,432,172, is 1.

Now, the common factors can be found like this.

857:857

611:13x 47

432:2x 2x 2x 2x 3x 3x 3

172:2x 2x 43

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 = 38907580608/(1x4)

LCM = 38907580608/4

LCM = 9726895152

Thus, we can understand that the LCM of 857,611,432,172 is 9726895152.
