Calculate the LCM of 961,771,865,804

Given numbers are 961,771,865,804

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

The LCM of 961,771,865,804 is 171762624420.

Find LCM of 961,771,865,804 with Prime Factorization


3 961, 771, 865, 804
961, 257, 865, 268

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

3 x 961 x 257 x 865 x 268 = 171762624420

Therefore, the lowest common multiple of 961,771,865,804 is 171762624420.

LCM Formula to Find Lowest Common Multiple of 961,771,865,804

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.

961 x 771 x 865 x 804 = 515287873260

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.

961 : 1, 31, 961

771 : 1, 3, 257, 771

865 : 1, 5, 173, 865

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,771,865,804, is 1.

Now, the common factors can be found like this.

961:31x 31

771:3x 257

865:5x 173

804:2x 2x 3x 67

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 = 515287873260/(1x3)

LCM = 515287873260/3

LCM = 171762624420

Thus, we can understand that the LCM of 961,771,865,804 is 171762624420.
