Calculate the LCM of 869,841,868,770

Given numbers are 869,841,868,770

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

The LCM of 869,841,868,770 is 3171797860.

Find LCM of 869,841,868,770 with Prime Factorization


2 869, 841, 868, 770
7 869, 841, 434, 385
11 869, 841, 62, 55
79, 841, 62, 5

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

2 x 7 x 11 x 79 x 841 x 62 x 5 = 3171797860

Therefore, the lowest common multiple of 869,841,868,770 is 3171797860.

LCM Formula to Find Lowest Common Multiple of 869,841,868,770

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.

869 x 841 x 868 x 770 = 488456870440

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.

869 : 1, 11, 79, 869

841 : 1, 29, 841

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,841,868,770, is 1.

Now, the common factors can be found like this.

869:11x 79

841:29x 29

868:2x 2x 7x 31

770:2x 5x 7x 11

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

2x 7x 11 = 154

Therefore, the value for common factors is 154.

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 = 488456870440/(1x154)

LCM = 488456870440/154

LCM = 3171797860

Thus, we can understand that the LCM of 869,841,868,770 is 3171797860.
