LCM of:

Calculate the LCM of 691,162,370

Given numbers are 691,162,370

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

The LCM of 691,162,370 is 20709270.

Find LCM of 691,162,370 with Prime Factorization


2 691, 162, 370
691, 81, 185

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

2 x 691 x 81 x 185 = 20709270

Therefore, the lowest common multiple of 691,162,370 is 20709270.

LCM Formula to Find Lowest Common Multiple of 691,162,370

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 162 x 370 = 41418540

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

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

370 : 1, 2, 5, 10, 37, 74, 185, 370

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,162,370, is 1.

Now, the common factors can be found like this.

691:691

162:2x 3x 3x 3x 3

370:2x 5x 37

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

2 = 2

Therefore, the value for common factors is 2.

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 = 41418540/(1x2)

LCM = 41418540/2

LCM = 20709270

Thus, we can understand that the LCM of 691,162,370 is 20709270.
