Calculate the LCM of 686,649,933,423,620

Given numbers are 686,649,933,423,620

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

The LCM of 686,649,933,423,620 is 18156463576020.

Find LCM of 686,649,933,423,620 with Prime Factorization


2 686, 649, 933, 423, 620
3 343, 649, 933, 423, 310
343, 649, 311, 141, 310

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

2 x 3 x 343 x 649 x 311 x 141 x 310 = 18156463576020

Therefore, the lowest common multiple of 686,649,933,423,620 is 18156463576020.

LCM Formula to Find Lowest Common Multiple of 686,649,933,423,620

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 649 x 933 x 423 x 620 = 108938781456120

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

649 : 1, 11, 59, 649

933 : 1, 3, 311, 933

423 : 1, 3, 9, 47, 141, 423

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,649,933,423,620, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

649:11x 59

933:3x 311

423:3x 3x 47

620:2x 2x 5x 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 3 = 6

Therefore, the value for common factors is 6.

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 = 108938781456120/(1x6)

LCM = 108938781456120/6

LCM = 18156463576020

Thus, we can understand that the LCM of 686,649,933,423,620 is 18156463576020.
