Calculate the LCM of 477,440,361,821,678

Given numbers are 477,440,361,821,678

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

The LCM of 477,440,361,821,678 is 7029102203640.

Find LCM of 477,440,361,821,678 with Prime Factorization


2 477, 440, 361, 821, 678
3 477, 220, 361, 821, 339
159, 220, 361, 821, 113

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

2 x 3 x 159 x 220 x 361 x 821 x 113 = 7029102203640

Therefore, the lowest common multiple of 477,440,361,821,678 is 7029102203640.

LCM Formula to Find Lowest Common Multiple of 477,440,361,821,678

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.

477 x 440 x 361 x 821 x 678 = 42174613221840

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.

477 : 1, 3, 9, 53, 159, 477

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

361 : 1, 19, 361

821 : 1, 821

678 : 1, 2, 3, 6, 113, 226, 339, 678

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,440,361,821,678, is 1.

Now, the common factors can be found like this.

477:3x 3x 53

440:2x 2x 2x 5x 11

361:19x 19

821:821

678:2x 3x 113

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 = 42174613221840/(1x6)

LCM = 42174613221840/6

LCM = 7029102203640

Thus, we can understand that the LCM of 477,440,361,821,678 is 7029102203640.
