Find LCM of 280,556,266,494,789 with Prime Factorization


2 280, 556, 266, 494, 789
2 140, 278, 133, 247, 789
7 70, 139, 133, 247, 789
19 10, 139, 19, 247, 789
10, 139, 1, 13, 789

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

2 x 2 x 7 x 19 x 10 x 139 x 1 x 13 x 789 = 7584846360

Therefore, the lowest common multiple of 280,556,266,494,789 is 7584846360.

LCM Formula to Find Lowest Common Multiple of 280,556,266,494,789

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.

280 x 556 x 266 x 494 x 789 = 16140553054080

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.

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

556 : 1, 2, 4, 139, 278, 556

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

494 : 1, 2, 13, 19, 26, 38, 247, 494

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,556,266,494,789, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

556:2x 2x 139

266:2x 7x 19

494:2x 13x 19

789:3x 263

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 7x 19 = 2128

Therefore, the value for common factors is 2128.

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 = 16140553054080/(1x2128)

LCM = 16140553054080/2128

LCM = 7584846360

Thus, we can understand that the LCM of 280,556,266,494,789 is 7584846360.
