Calculate the LCM of 855,845,767,665

Given numbers are 855,845,767,665

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

The LCM of 855,845,767,665 is 59676435.

Find LCM of 855,845,767,665 with Prime Factorization


5 855, 845, 767, 665
13 171, 169, 767, 133
19 171, 13, 59, 133
9, 13, 59, 7

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

5 x 13 x 19 x 9 x 13 x 59 x 7 = 59676435

Therefore, the lowest common multiple of 855,845,767,665 is 59676435.

LCM Formula to Find Lowest Common Multiple of 855,845,767,665

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.

855 x 845 x 767 x 665 = 368501986125

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

845 : 1, 5, 13, 65, 169, 845

767 : 1, 13, 59, 767

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,845,767,665, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

845:5x 13x 13

767:13x 59

665:5x 7x 19

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

5x 5x 13x 19 = 6175

Therefore, the value for common factors is 6175.

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 = 368501986125/(1x6175)

LCM = 368501986125/6175

LCM = 59676435

Thus, we can understand that the LCM of 855,845,767,665 is 59676435.
