Given numbers are 622,149,645,903

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

The LCM of 622,149,645,903 is 418441170.

Find LCM of 622,149,645,903 with Prime Factorization

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

3 x 43 x 622 x 149 x 5 x 7 = 418441170

Therefore, the lowest common multiple of 622,149,645,903 is 418441170.

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.

622 x 149 x 645 x 903 = 53978910930

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.

622 : 1, 2, 311, 622

149 : 1, 149

645 : 1, 3, 5, 15, 43, 129, 215, 645

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,149,645,903, is 1.

Now, the common factors can be found like this.

622:2x 311

149:149

645:3x 5x 43

903:3x 7x 43

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

3x 43 = 129

Therefore, the value for common factors is 129.

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 = 53978910930/(1x129)

LCM = 53978910930/129

LCM = 418441170

Thus, we can understand that the LCM of 622,149,645,903 is 418441170.
