Given numbers are 791,128,716,988

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

The LCM of 791,128,716,988 is 4476477824.

Find LCM of 791,128,716,988 with Prime Factorization

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

2 x 2 x 791 x 32 x 179 x 247 = 4476477824

Therefore, the lowest common multiple of 791,128,716,988 is 4476477824.

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.

791 x 128 x 716 x 988 = 71623645184

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.

791 : 1, 7, 113, 791

128 : 1, 2, 4, 8, 16, 32, 64, 128

716 : 1, 2, 4, 179, 358, 716

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,128,716,988, is 1.

Now, the common factors can be found like this.

791:7x 113

128:2x 2x 2x 2x 2x 2x 2

716:2x 2x 179

988:2x 2x 13x 19

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 71623645184/(1x16)

LCM = 71623645184/16

LCM = 4476477824

Thus, we can understand that the LCM of 791,128,716,988 is 4476477824.
