Given numbers are 686,820,523,124

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

The LCM of 686,820,523,124 is 4560068380.

Find LCM of 686,820,523,124 with Prime Factorization

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

2 x 2 x 343 x 205 x 523 x 31 = 4560068380

Therefore, the lowest common multiple of 686,820,523,124 is 4560068380.

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 820 x 523 x 124 = 36480547040

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

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

523 : 1, 523

124 : 1, 2, 4, 31, 62, 124

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,820,523,124, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

820:2x 2x 5x 41

523:523

124:2x 2x 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 2 = 8

Therefore, the value for common factors is 8.

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 = 36480547040/(1x8)

LCM = 36480547040/8

LCM = 4560068380

Thus, we can understand that the LCM of 686,820,523,124 is 4560068380.
