Given numbers are 793,638,427,428

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

The LCM of 793,638,427,428 is 757889132.

Find LCM of 793,638,427,428 with Prime Factorization

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

2 x 61 x 13 x 319 x 7 x 214 = 757889132

Therefore, the lowest common multiple of 793,638,427,428 is 757889132.

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.

793 x 638 x 427 x 428 = 92462474104

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.

793 : 1, 13, 61, 793

638 : 1, 2, 11, 22, 29, 58, 319, 638

427 : 1, 7, 61, 427

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,638,427,428, is 1.

Now, the common factors can be found like this.

793:13x 61

638:2x 11x 29

427:7x 61

428:2x 2x 107

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

2x 61 = 122

Therefore, the value for common factors is 122.

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 = 92462474104/(1x122)

LCM = 92462474104/122

LCM = 757889132

Thus, we can understand that the LCM of 793,638,427,428 is 757889132.
