Calculate the LCM of 770,195,242

Given numbers are 770,195,242

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

The LCM of 770,195,242 is 330330.

Find LCM of 770,195,242 with Prime Factorization


2 770, 195, 242
5 385, 195, 121
11 77, 39, 121
7, 39, 11

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

2 x 5 x 11 x 7 x 39 x 11 = 330330

Therefore, the lowest common multiple of 770,195,242 is 330330.

LCM Formula to Find Lowest Common Multiple of 770,195,242

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.

770 x 195 x 242 = 36336300

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.

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

195 : 1, 3, 5, 13, 15, 39, 65, 195

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,195,242, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

195:3x 5x 13

242:2x 11x 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 5x 11 = 110

Therefore, the value for common factors is 110.

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 = 36336300/(1x110)

LCM = 36336300/110

LCM = 330330

Thus, we can understand that the LCM of 770,195,242 is 330330.
