Given numbers are 189,474,912,457

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

The LCM of 189,474,912,457 is 2074333968.

Find LCM of 189,474,912,457 with Prime Factorization

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

2 x 3 x 63 x 79 x 152 x 457 = 2074333968

Therefore, the lowest common multiple of 189,474,912,457 is 2074333968.

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.

189 x 474 x 912 x 457 = 37338011424

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

474 : 1, 2, 3, 6, 79, 158, 237, 474

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,474,912,457, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

474:2x 3x 79

912:2x 2x 2x 2x 3x 19

457:457

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 = 37338011424/(1x18)

LCM = 37338011424/18

LCM = 2074333968

Thus, we can understand that the LCM of 189,474,912,457 is 2074333968.
