Given numbers are 421,764,257,742

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

The LCM of 421,764,257,742 is 30667790468.

Find LCM of 421,764,257,742 with Prime Factorization

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

2 x 421 x 382 x 257 x 371 = 30667790468

Therefore, the lowest common multiple of 421,764,257,742 is 30667790468.

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.

421 x 764 x 257 x 742 = 61335580936

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.

421 : 1, 421

764 : 1, 2, 4, 191, 382, 764

257 : 1, 257

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,764,257,742, is 1.

Now, the common factors can be found like this.

421:421

764:2x 2x 191

257:257

742:2x 7x 53

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 = 61335580936/(1x2)

LCM = 61335580936/2

LCM = 30667790468

Thus, we can understand that the LCM of 421,764,257,742 is 30667790468.
