Given numbers are 403,508,155,921

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

The LCM of 403,508,155,921 is 942754020.

Find LCM of 403,508,155,921 with Prime Factorization

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

31 x 13 x 508 x 5 x 921 = 942754020

Therefore, the lowest common multiple of 403,508,155,921 is 942754020.

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.

403 x 508 x 155 x 921 = 29225374620

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.

403 : 1, 13, 31, 403

508 : 1, 2, 4, 127, 254, 508

155 : 1, 5, 31, 155

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,508,155,921, is 1.

Now, the common factors can be found like this.

403:13x 31

508:2x 2x 127

155:5x 31

921:3x 307

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

31 = 31

Therefore, the value for common factors is 31.

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 = 29225374620/(1x31)

LCM = 29225374620/31

LCM = 942754020

Thus, we can understand that the LCM of 403,508,155,921 is 942754020.
