Given numbers are 620,381,921,366,936

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

The LCM of 620,381,921,366,936 is 345047971320.

Find LCM of 620,381,921,366,936 with Prime Factorization

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

2 x 2 x 3 x 155 x 127 x 307 x 61 x 78 = 345047971320

Therefore, the lowest common multiple of 620,381,921,366,936 is 345047971320.

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.

620 x 381 x 921 x 366 x 936 = 74530361805120

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.

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

381 : 1, 3, 127, 381

921 : 1, 3, 307, 921

366 : 1, 2, 3, 6, 61, 122, 183, 366

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,381,921,366,936, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

381:3x 127

921:3x 307

366:2x 3x 61

936:2x 2x 2x 3x 3x 13

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 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 74530361805120/(1x216)

LCM = 74530361805120/216

LCM = 345047971320

Thus, we can understand that the LCM of 620,381,921,366,936 is 345047971320.
