Given numbers are 241,437,420,742

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

The LCM of 241,437,420,742 is 2344356420.

Find LCM of 241,437,420,742 with Prime Factorization

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

2 x 7 x 241 x 437 x 30 x 53 = 2344356420

Therefore, the lowest common multiple of 241,437,420,742 is 2344356420.

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.

241 x 437 x 420 x 742 = 32820989880

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.

241 : 1, 241

437 : 1, 19, 23, 437

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

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 241,437,420,742, is 1.

Now, the common factors can be found like this.

241:241

437:19x 23

420:2x 2x 3x 5x 7

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.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 32820989880/(1x14)

LCM = 32820989880/14

LCM = 2344356420

Thus, we can understand that the LCM of 241,437,420,742 is 2344356420.
