Given numbers are 742,257,771,977

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

The LCM of 742,257,771,977 is 558924114.

Find LCM of 742,257,771,977 with Prime Factorization

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

257 x 742 x 1 x 3 x 977 = 558924114

Therefore, the lowest common multiple of 742,257,771,977 is 558924114.

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.

742 x 257 x 771 x 977 = 143643497298

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

257 : 1, 257

771 : 1, 3, 257, 771

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,257,771,977, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

257:257

771:3x 257

977:977

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 = 143643497298/(1x257)

LCM = 143643497298/257

LCM = 558924114

Thus, we can understand that the LCM of 742,257,771,977 is 558924114.
