Given numbers are 257,203,113,145

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

The LCM of 257,203,113,145 is 29476615.

Find LCM of 257,203,113,145 with Prime Factorization

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

29 x 257 x 7 x 113 x 5 = 29476615

Therefore, the lowest common multiple of 257,203,113,145 is 29476615.

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.

257 x 203 x 113 x 145 = 854821835

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.

257 : 1, 257

203 : 1, 7, 29, 203

113 : 1, 113

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,203,113,145, is 1.

Now, the common factors can be found like this.

257:257

203:7x 29

113:113

145:5x 29

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

29 = 29

Therefore, the value for common factors is 29.

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 = 854821835/(1x29)

LCM = 854821835/29

LCM = 29476615

Thus, we can understand that the LCM of 257,203,113,145 is 29476615.

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

• LCM of 895, 733, 726, 374
