Given numbers are 686,790,812,290,372

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

The LCM of 686,790,812,290,372 is 1461612180.

Find LCM of 686,790,812,290,372 with Prime Factorization

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

2 x 2 x 5 x 7 x 29 x 49 x 79 x 1 x 1 x 93 = 1461612180

Therefore, the lowest common multiple of 686,790,812,290,372 is 1461612180.

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 790 x 812 x 290 x 372 = 47473163606400

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

790 : 1, 2, 5, 10, 79, 158, 395, 790

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

290 : 1, 2, 5, 10, 29, 58, 145, 290

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,790,812,290,372, is 2.

Now, the common factors can be found like this.

686:2x 7x 7x 7

790:2x 5x 79

812:2x 2x 7x 29

290:2x 5x 29

372:2x 2x 3x 31

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 5x 7x 29 = 16240

Therefore, the value for common factors is 16240.

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 = 47473163606400/(2x16240)

LCM = 47473163606400/32480

LCM = 1461612180

Thus, we can understand that the LCM of 686,790,812,290,372 is 1461612180.
