Calculate the LCM of 169,640,645,977

Given numbers are 169,640,645,977

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

The LCM of 169,640,645,977 is 13631729280.

Find LCM of 169,640,645,977 with Prime Factorization


5 169, 640, 645, 977
169, 128, 129, 977

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

5 x 169 x 128 x 129 x 977 = 13631729280

Therefore, the lowest common multiple of 169,640,645,977 is 13631729280.

LCM Formula to Find Lowest Common Multiple of 169,640,645,977

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.

169 x 640 x 645 x 977 = 68158646400

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.

169 : 1, 13, 169

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

645 : 1, 3, 5, 15, 43, 129, 215, 645

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,640,645,977, is 1.

Now, the common factors can be found like this.

169:13x 13

640:2x 2x 2x 2x 2x 2x 2x 5

645:3x 5x 43

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.

5 = 5

Therefore, the value for common factors is 5.

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 = 68158646400/(1x5)

LCM = 68158646400/5

LCM = 13631729280

Thus, we can understand that the LCM of 169,640,645,977 is 13631729280.
