Given numbers are 257,604,151,821

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

The LCM of 257,604,151,821 is 127442188.

Find LCM of 257,604,151,821 with Prime Factorization

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

151 x 257 x 4 x 1 x 821 = 127442188

Therefore, the lowest common multiple of 257,604,151,821 is 127442188.

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 604 x 151 x 821 = 19243770388

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

604 : 1, 2, 4, 151, 302, 604

151 : 1, 151

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,604,151,821, is 1.

Now, the common factors can be found like this.

257:257

604:2x 2x 151

151:151

821:821

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

151 = 151

Therefore, the value for common factors is 151.

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 = 19243770388/(1x151)

LCM = 19243770388/151

LCM = 127442188

Thus, we can understand that the LCM of 257,604,151,821 is 127442188.
