Given numbers are 151,642,130,172

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

The LCM of 151,642,130,172 is 541905780.

Find LCM of 151,642,130,172 with Prime Factorization

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

2 x 151 x 321 x 65 x 86 = 541905780

Therefore, the lowest common multiple of 151,642,130,172 is 541905780.

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.

151 x 642 x 130 x 172 = 2167623120

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.

151 : 1, 151

642 : 1, 2, 3, 6, 107, 214, 321, 642

130 : 1, 2, 5, 10, 13, 26, 65, 130

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 151,642,130,172, is 1.

Now, the common factors can be found like this.

151:151

642:2x 3x 107

130:2x 5x 13

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 = 2167623120/(1x4)

LCM = 2167623120/4

LCM = 541905780

Thus, we can understand that the LCM of 151,642,130,172 is 541905780.
