Given numbers are 672,781,266,261,691

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

The LCM of 672,781,266,261,691 is 599475181536.

Find LCM of 672,781,266,261,691 with Prime Factorization

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

2 x 3 x 7 x 16 x 781 x 19 x 87 x 691 = 599475181536

Therefore, the lowest common multiple of 672,781,266,261,691 is 599475181536.

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.

672 x 781 x 266 x 261 x 691 = 25177957624512

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.

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

781 : 1, 11, 71, 781

266 : 1, 2, 7, 14, 19, 38, 133, 266

261 : 1, 3, 9, 29, 87, 261

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,781,266,261,691, is 1.

Now, the common factors can be found like this.

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

781:11x 71

266:2x 7x 19

261:3x 3x 29

691:691

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 25177957624512/(1x42)

LCM = 25177957624512/42

LCM = 599475181536

Thus, we can understand that the LCM of 672,781,266,261,691 is 599475181536.
