Given numbers are 857,697,689,143

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

The LCM of 857,697,689,143 is 4527156491.

Find LCM of 857,697,689,143 with Prime Factorization

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

13 x 857 x 697 x 53 x 11 = 4527156491

Therefore, the lowest common multiple of 857,697,689,143 is 4527156491.

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 697 x 689 x 143 = 58853034383

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

697 : 1, 17, 41, 697

689 : 1, 13, 53, 689

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,697,689,143, is 1.

Now, the common factors can be found like this.

857:857

697:17x 41

689:13x 53

143:11x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 58853034383/(1x13)

LCM = 58853034383/13

LCM = 4527156491

Thus, we can understand that the LCM of 857,697,689,143 is 4527156491.
