Calculate the LCM of 669,529,825,770

Given numbers are 669,529,825,770

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

The LCM of 669,529,825,770 is 1362518850.

Find LCM of 669,529,825,770 with Prime Factorization


3 669, 529, 825, 770
5 223, 529, 275, 770
11 223, 529, 55, 154
223, 529, 5, 14

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

3 x 5 x 11 x 223 x 529 x 5 x 14 = 1362518850

Therefore, the lowest common multiple of 669,529,825,770 is 1362518850.

LCM Formula to Find Lowest Common Multiple of 669,529,825,770

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.

669 x 529 x 825 x 770 = 224815610250

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.

669 : 1, 3, 223, 669

529 : 1, 23, 529

825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,529,825,770, is 1.

Now, the common factors can be found like this.

669:3x 223

529:23x 23

825:3x 5x 5x 11

770:2x 5x 7x 11

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

3x 5x 11 = 165

Therefore, the value for common factors is 165.

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 = 224815610250/(1x165)

LCM = 224815610250/165

LCM = 1362518850

Thus, we can understand that the LCM of 669,529,825,770 is 1362518850.
