Given numbers are 658,188,221,401

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

The LCM of 658,188,221,401 is 116625236.

Find LCM of 658,188,221,401 with Prime Factorization

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

2 x 47 x 7 x 2 x 221 x 401 = 116625236

Therefore, the lowest common multiple of 658,188,221,401 is 116625236.

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.

658 x 188 x 221 x 401 = 10962772184

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

188 : 1, 2, 4, 47, 94, 188

221 : 1, 13, 17, 221

401 : 1, 401

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,188,221,401, is 1.

Now, the common factors can be found like this.

658:2x 7x 47

188:2x 2x 47

221:13x 17

401:401

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

2x 47 = 94

Therefore, the value for common factors is 94.

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 = 10962772184/(1x94)

LCM = 10962772184/94

LCM = 116625236

Thus, we can understand that the LCM of 658,188,221,401 is 116625236.
