Given numbers are 651,672,474,816

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

The LCM of 651,672,474,816 is 27977376.

Find LCM of 651,672,474,816 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 7 x 31 x 2 x 79 x 17 = 27977376

Therefore, the lowest common multiple of 651,672,474,816 is 27977376.

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.

651 x 672 x 474 x 816 = 169207170048

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.

651 : 1, 3, 7, 21, 31, 93, 217, 651

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

474 : 1, 2, 3, 6, 79, 158, 237, 474

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,672,474,816, is 3.

Now, the common factors can be found like this.

651:3x 7x 31

672:2x 2x 2x 2x 2x 3x 7

474:2x 3x 79

816:2x 2x 2x 2x 3x 17

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 2x 3x 3x 7 = 2016

Therefore, the value for common factors is 2016.

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 = 169207170048/(3x2016)

LCM = 169207170048/6048

LCM = 27977376

Thus, we can understand that the LCM of 651,672,474,816 is 27977376.
