Given numbers are 638,157,188

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

The LCM of 638,157,188 is 9415604.

Find LCM of 638,157,188 with Prime Factorization

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

2 x 319 x 157 x 94 = 9415604

Therefore, the lowest common multiple of 638,157,188 is 9415604.

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.

638 x 157 x 188 = 18831208

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

157 : 1, 157

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,157,188, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

157:157

188:2x 2x 47

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

2 = 2

Therefore, the value for common factors is 2.

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 = 18831208/(1x2)

LCM = 18831208/2

LCM = 9415604

Thus, we can understand that the LCM of 638,157,188 is 9415604.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 926, 778, 303
• LCM of 790, 101, 218
