Calculate the LCM of 421,988,471,717

Given numbers are 421,988,471,717

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

The LCM of 421,988,471,717 is 46822850412.

Find LCM of 421,988,471,717 with Prime Factorization


3 421, 988, 471, 717
421, 988, 157, 239

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

3 x 421 x 988 x 157 x 239 = 46822850412

Therefore, the lowest common multiple of 421,988,471,717 is 46822850412.

LCM Formula to Find Lowest Common Multiple of 421,988,471,717

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.

421 x 988 x 471 x 717 = 140468551236

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.

421 : 1, 421

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

471 : 1, 3, 157, 471

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,988,471,717, is 1.

Now, the common factors can be found like this.

421:421

988:2x 2x 13x 19

471:3x 157

717:3x 239

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

3 = 3

Therefore, the value for common factors is 3.

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 = 140468551236/(1x3)

LCM = 140468551236/3

LCM = 46822850412

Thus, we can understand that the LCM of 421,988,471,717 is 46822850412.
