Given numbers are 749,253,161,669

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

The LCM of 749,253,161,669 is 126773493.

Find LCM of 749,253,161,669 with Prime Factorization

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

7 x 23 x 107 x 11 x 1 x 669 = 126773493

Therefore, the lowest common multiple of 749,253,161,669 is 126773493.

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.

749 x 253 x 161 x 669 = 20410532373

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.

749 : 1, 7, 107, 749

253 : 1, 11, 23, 253

161 : 1, 7, 23, 161

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,253,161,669, is 1.

Now, the common factors can be found like this.

749:7x 107

253:11x 23

161:7x 23

669:3x 223

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 20410532373/(1x161)

LCM = 20410532373/161

LCM = 126773493

Thus, we can understand that the LCM of 749,253,161,669 is 126773493.
