Given numbers are 751,278,209,986

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

The LCM of 751,278,209,986 is 21511858786.

Find LCM of 751,278,209,986 with Prime Factorization

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

2 x 751 x 139 x 209 x 493 = 21511858786

Therefore, the lowest common multiple of 751,278,209,986 is 21511858786.

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.

751 x 278 x 209 x 986 = 43023717572

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.

751 : 1, 751

278 : 1, 2, 139, 278

209 : 1, 11, 19, 209

986 : 1, 2, 17, 29, 34, 58, 493, 986

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,278,209,986, is 1.

Now, the common factors can be found like this.

751:751

278:2x 139

209:11x 19

986:2x 17x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 43023717572/(1x2)

LCM = 43023717572/2

LCM = 21511858786

Thus, we can understand that the LCM of 751,278,209,986 is 21511858786.
