Calculate the LCM of 345,691,765,956

Given numbers are 345,691,765,956

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

The LCM of 345,691,765,956 is 11623186620.

Find LCM of 345,691,765,956 with Prime Factorization


3 345, 691, 765, 956
5 115, 691, 255, 956
23, 691, 51, 956

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

3 x 5 x 23 x 691 x 51 x 956 = 11623186620

Therefore, the lowest common multiple of 345,691,765,956 is 11623186620.

LCM Formula to Find Lowest Common Multiple of 345,691,765,956

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.

345 x 691 x 765 x 956 = 174347799300

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

691 : 1, 691

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

956 : 1, 2, 4, 239, 478, 956

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,691,765,956, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

691:691

765:3x 3x 5x 17

956:2x 2x 239

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 174347799300/(1x15)

LCM = 174347799300/15

LCM = 11623186620

Thus, we can understand that the LCM of 345,691,765,956 is 11623186620.
