Given numbers are 688,558,534,306,965

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

The LCM of 688,558,534,306,965 is 280258557840.

Find LCM of 688,558,534,306,965 with Prime Factorization

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

2 x 3 x 3 x 344 x 31 x 89 x 17 x 965 = 280258557840

Therefore, the lowest common multiple of 688,558,534,306,965 is 280258557840.

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.

688 x 558 x 534 x 306 x 965 = 60535848493440

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

534 : 1, 2, 3, 6, 89, 178, 267, 534

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

965 : 1, 5, 193, 965

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,558,534,306,965, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

558:2x 3x 3x 31

534:2x 3x 89

306:2x 3x 3x 17

965:5x 193

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 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 60535848493440/(1x216)

LCM = 60535848493440/216

LCM = 280258557840

Thus, we can understand that the LCM of 688,558,534,306,965 is 280258557840.
