Given numbers are 742,548,391,274

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

The LCM of 742,548,391,274 is 79493428.

Find LCM of 742,548,391,274 with Prime Factorization

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

2 x 137 x 371 x 2 x 391 x 1 = 79493428

Therefore, the lowest common multiple of 742,548,391,274 is 79493428.

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 548 x 391 x 274 = 43562398544

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

548 : 1, 2, 4, 137, 274, 548

391 : 1, 17, 23, 391

274 : 1, 2, 137, 274

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,548,391,274, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

548:2x 2x 137

391:17x 23

274:2x 137

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

2x 2x 137 = 548

Therefore, the value for common factors is 548.

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 = 43562398544/(1x548)

LCM = 43562398544/548

LCM = 79493428

Thus, we can understand that the LCM of 742,548,391,274 is 79493428.
