Calculate the LCM of 422,399,977,977

Given numbers are 422,399,977,977

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

The LCM of 422,399,977,977 is 164505306.

Find LCM of 422,399,977,977 with Prime Factorization


977 422, 399, 977, 977
422, 399, 1, 1

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

977 x 422 x 399 x 1 x 1 = 164505306

Therefore, the lowest common multiple of 422,399,977,977 is 164505306.

LCM Formula to Find Lowest Common Multiple of 422,399,977,977

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.

422 x 399 x 977 x 977 = 160721683962

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.

422 : 1, 2, 211, 422

399 : 1, 3, 7, 19, 21, 57, 133, 399

977 : 1, 977

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,399,977,977, is 1.

Now, the common factors can be found like this.

422:2x 211

399:3x 7x 19

977:977

977:977

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

977 = 977

Therefore, the value for common factors is 977.

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 = 160721683962/(1x977)

LCM = 160721683962/977

LCM = 164505306

Thus, we can understand that the LCM of 422,399,977,977 is 164505306.
