Calculate the LCM of 821,622,996,985

Given numbers are 821,622,996,985

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

The LCM of 821,622,996,985 is 250495030860.

Find LCM of 821,622,996,985 with Prime Factorization


2 821, 622, 996, 985
821, 311, 498, 985

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

2 x 821 x 311 x 498 x 985 = 250495030860

Therefore, the lowest common multiple of 821,622,996,985 is 250495030860.

LCM Formula to Find Lowest Common Multiple of 821,622,996,985

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.

821 x 622 x 996 x 985 = 500990061720

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.

821 : 1, 821

622 : 1, 2, 311, 622

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,622,996,985, is 1.

Now, the common factors can be found like this.

821:821

622:2x 311

996:2x 2x 3x 83

985:5x 197

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 500990061720/(1x2)

LCM = 500990061720/2

LCM = 250495030860

Thus, we can understand that the LCM of 821,622,996,985 is 250495030860.
