Given numbers are 790,988,798,532,991

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

The LCM of 790,988,798,532,991 is 8121700860.

Find LCM of 790,988,798,532,991 with Prime Factorization

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

2 x 2 x 7 x 19 x 395 x 13 x 3 x 1 x 991 = 8121700860

Therefore, the lowest common multiple of 790,988,798,532,991 is 8121700860.

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.

790 x 988 x 798 x 532 x 991 = 328376609171520

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.

790 : 1, 2, 5, 10, 79, 158, 395, 790

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

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,988,798,532,991, is 1.

Now, the common factors can be found like this.

790:2x 5x 79

988:2x 2x 13x 19

798:2x 3x 7x 19

532:2x 2x 7x 19

991:991

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 2x 7x 19x 19 = 40432

Therefore, the value for common factors is 40432.

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 = 328376609171520/(1x40432)

LCM = 328376609171520/40432

LCM = 8121700860

Thus, we can understand that the LCM of 790,988,798,532,991 is 8121700860.
