Calculate the LCM of 890,836,704,284

Given numbers are 890,836,704,284

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

The LCM of 890,836,704,284 is 422614720.

Find LCM of 890,836,704,284 with Prime Factorization


2 890, 836, 704, 284
2 445, 418, 352, 142
11 445, 209, 176, 71
445, 19, 16, 71

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

2 x 2 x 11 x 445 x 19 x 16 x 71 = 422614720

Therefore, the lowest common multiple of 890,836,704,284 is 422614720.

LCM Formula to Find Lowest Common Multiple of 890,836,704,284

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.

890 x 836 x 704 x 284 = 148760381440

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.

890 : 1, 2, 5, 10, 89, 178, 445, 890

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

284 : 1, 2, 4, 71, 142, 284

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,836,704,284, is 2.

Now, the common factors can be found like this.

890:2x 5x 89

836:2x 2x 11x 19

704:2x 2x 2x 2x 2x 2x 11

284:2x 2x 71

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 11 = 176

Therefore, the value for common factors is 176.

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 = 148760381440/(2x176)

LCM = 148760381440/352

LCM = 422614720

Thus, we can understand that the LCM of 890,836,704,284 is 422614720.
