Given numbers are 153,642,669,338

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

The LCM of 153,642,669,338 is 1233947754.

Find LCM of 153,642,669,338 with Prime Factorization

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

2 x 3 x 51 x 107 x 223 x 169 = 1233947754

Therefore, the lowest common multiple of 153,642,669,338 is 1233947754.

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.

153 x 642 x 669 x 338 = 22211059572

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.

153 : 1, 3, 9, 17, 51, 153

642 : 1, 2, 3, 6, 107, 214, 321, 642

669 : 1, 3, 223, 669

338 : 1, 2, 13, 26, 169, 338

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,642,669,338, is 1.

Now, the common factors can be found like this.

153:3x 3x 17

642:2x 3x 107

669:3x 223

338:2x 13x 13

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 22211059572/(1x18)

LCM = 22211059572/18

LCM = 1233947754

Thus, we can understand that the LCM of 153,642,669,338 is 1233947754.
