Calculate the LCM of 628,198,608,869

Given numbers are 628,198,608,869

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

The LCM of 628,198,608,869 is 746561376.

Find LCM of 628,198,608,869 with Prime Factorization


2 628, 198, 608, 869
2 314, 99, 304, 869
11 157, 99, 152, 869
157, 9, 152, 79

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

2 x 2 x 11 x 157 x 9 x 152 x 79 = 746561376

Therefore, the lowest common multiple of 628,198,608,869 is 746561376.

LCM Formula to Find Lowest Common Multiple of 628,198,608,869

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.

628 x 198 x 608 x 869 = 65697401088

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.

628 : 1, 2, 4, 157, 314, 628

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

869 : 1, 11, 79, 869

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,198,608,869, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

198:2x 3x 3x 11

608:2x 2x 2x 2x 2x 19

869:11x 79

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

2x 2x 2x 11 = 88

Therefore, the value for common factors is 88.

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 = 65697401088/(1x88)

LCM = 65697401088/88

LCM = 746561376

Thus, we can understand that the LCM of 628,198,608,869 is 746561376.
