Given numbers are 669,421,903,174

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

The LCM of 669,421,903,174 is 4917028242.

Find LCM of 669,421,903,174 with Prime Factorization

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

3 x 223 x 421 x 301 x 58 = 4917028242

Therefore, the lowest common multiple of 669,421,903,174 is 4917028242.

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 421 x 903 x 174 = 44253254178

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

421 : 1, 421

903 : 1, 3, 7, 21, 43, 129, 301, 903

174 : 1, 2, 3, 6, 29, 58, 87, 174

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,421,903,174, is 1.

Now, the common factors can be found like this.

669:3x 223

421:421

903:3x 7x 43

174:2x 3x 29

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 44253254178/(1x9)

LCM = 44253254178/9

LCM = 4917028242

Thus, we can understand that the LCM of 669,421,903,174 is 4917028242.
