Given numbers are 771,257,151,857

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

The LCM of 771,257,151,857 is 99772797.

Find LCM of 771,257,151,857 with Prime Factorization

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

257 x 3 x 1 x 151 x 857 = 99772797

Therefore, the lowest common multiple of 771,257,151,857 is 99772797.

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.

771 x 257 x 151 x 857 = 25641608829

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.

771 : 1, 3, 257, 771

257 : 1, 257

151 : 1, 151

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,257,151,857, is 1.

Now, the common factors can be found like this.

771:3x 257

257:257

151:151

857:857

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

257 = 257

Therefore, the value for common factors is 257.

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 = 25641608829/(1x257)

LCM = 25641608829/257

LCM = 99772797

Thus, we can understand that the LCM of 771,257,151,857 is 99772797.
