Given numbers are 918,165,472,821

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

The LCM of 918,165,472,821 is 9782740440.

Find LCM of 918,165,472,821 with Prime Factorization

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

2 x 3 x 153 x 55 x 236 x 821 = 9782740440

Therefore, the lowest common multiple of 918,165,472,821 is 9782740440.

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.

918 x 165 x 472 x 821 = 58696442640

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.

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

165 : 1, 3, 5, 11, 15, 33, 55, 165

472 : 1, 2, 4, 8, 59, 118, 236, 472

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,165,472,821, is 1.

Now, the common factors can be found like this.

918:2x 3x 3x 3x 17

165:3x 5x 11

472:2x 2x 2x 59

821:821

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 = 58696442640/(1x6)

LCM = 58696442640/6

LCM = 9782740440

Thus, we can understand that the LCM of 918,165,472,821 is 9782740440.
