Given numbers are 668,704,672,787

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

The LCM of 668,704,672,787 is 1943046336.

Find LCM of 668,704,672,787 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 167 x 22 x 21 x 787 = 1943046336

Therefore, the lowest common multiple of 668,704,672,787 is 1943046336.

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.

668 x 704 x 672 x 787 = 248709931008

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.

668 : 1, 2, 4, 167, 334, 668

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

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

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,704,672,787, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

704:2x 2x 2x 2x 2x 2x 11

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

787:787

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 2x 2 = 128

Therefore, the value for common factors is 128.

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 = 248709931008/(1x128)

LCM = 248709931008/128

LCM = 1943046336

Thus, we can understand that the LCM of 668,704,672,787 is 1943046336.
