Calculate the LCM of 836,402,491,717

Given numbers are 836,402,491,717

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

The LCM of 836,402,491,717 is 19718856564.

Find LCM of 836,402,491,717 with Prime Factorization


2 836, 402, 491, 717
3 418, 201, 491, 717
418, 67, 491, 239

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

2 x 3 x 418 x 67 x 491 x 239 = 19718856564

Therefore, the lowest common multiple of 836,402,491,717 is 19718856564.

LCM Formula to Find Lowest Common Multiple of 836,402,491,717

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.

836 x 402 x 491 x 717 = 118313139384

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.

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

402 : 1, 2, 3, 6, 67, 134, 201, 402

491 : 1, 491

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,402,491,717, is 1.

Now, the common factors can be found like this.

836:2x 2x 11x 19

402:2x 3x 67

491:491

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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 118313139384/(1x6)

LCM = 118313139384/6

LCM = 19718856564

Thus, we can understand that the LCM of 836,402,491,717 is 19718856564.
