Given numbers are 686,407,247,377

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

The LCM of 686,407,247,377 is 1999923926.

Find LCM of 686,407,247,377 with Prime Factorization

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

13 x 686 x 407 x 19 x 29 = 1999923926

Therefore, the lowest common multiple of 686,407,247,377 is 1999923926.

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.

686 x 407 x 247 x 377 = 25999011038

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

407 : 1, 11, 37, 407

247 : 1, 13, 19, 247

377 : 1, 13, 29, 377

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,407,247,377, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

407:11x 37

247:13x 19

377:13x 29

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

13 = 13

Therefore, the value for common factors is 13.

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 = 25999011038/(1x13)

LCM = 25999011038/13

LCM = 1999923926

Thus, we can understand that the LCM of 686,407,247,377 is 1999923926.
