Calculate the LCM of 691,644,828,935

Given numbers are 691,644,828,935

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

The LCM of 691,644,828,935 is 3744708660.

Find LCM of 691,644,828,935 with Prime Factorization


2 691, 644, 828, 935
2 691, 322, 414, 935
23 691, 161, 207, 935
691, 7, 9, 935

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

2 x 2 x 23 x 691 x 7 x 9 x 935 = 3744708660

Therefore, the lowest common multiple of 691,644,828,935 is 3744708660.

LCM Formula to Find Lowest Common Multiple of 691,644,828,935

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.

691 x 644 x 828 x 935 = 344513196720

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.

691 : 1, 691

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

935 : 1, 5, 11, 17, 55, 85, 187, 935

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,644,828,935, is 1.

Now, the common factors can be found like this.

691:691

644:2x 2x 7x 23

828:2x 2x 3x 3x 23

935:5x 11x 17

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 23 = 92

Therefore, the value for common factors is 92.

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 = 344513196720/(1x92)

LCM = 344513196720/92

LCM = 3744708660

Thus, we can understand that the LCM of 691,644,828,935 is 3744708660.
