Given numbers are 420,182,266,984

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

The LCM of 420,182,266,984 is 8506680.

Find LCM of 420,182,266,984 with Prime Factorization

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

2 x 2 x 3 x 7 x 5 x 13 x 19 x 82 = 8506680

Therefore, the lowest common multiple of 420,182,266,984 is 8506680.

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.

420 x 182 x 266 x 984 = 20007711360

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

182 : 1, 2, 7, 13, 14, 26, 91, 182

266 : 1, 2, 7, 14, 19, 38, 133, 266

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,182,266,984, is 2.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

182:2x 7x 13

266:2x 7x 19

984:2x 2x 2x 3x 41

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 7x 7 = 1176

Therefore, the value for common factors is 1176.

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 = 20007711360/(2x1176)

LCM = 20007711360/2352

LCM = 8506680

Thus, we can understand that the LCM of 420,182,266,984 is 8506680.
