Given numbers are 157,214,856,742

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

The LCM of 157,214,856,742 is 49859432.

Find LCM of 157,214,856,742 with Prime Factorization

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

2 x 107 x 157 x 1 x 4 x 371 = 49859432

Therefore, the lowest common multiple of 157,214,856,742 is 49859432.

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.

157 x 214 x 856 x 742 = 21339836896

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.

157 : 1, 157

214 : 1, 2, 107, 214

856 : 1, 2, 4, 8, 107, 214, 428, 856

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,214,856,742, is 1.

Now, the common factors can be found like this.

157:157

214:2x 107

856:2x 2x 2x 107

742:2x 7x 53

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 107 = 428

Therefore, the value for common factors is 428.

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 = 21339836896/(1x428)

LCM = 21339836896/428

LCM = 49859432

Thus, we can understand that the LCM of 157,214,856,742 is 49859432.
