Given numbers are 390,157,451,403

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

The LCM of 390,157,451,403 is 856056630.

Find LCM of 390,157,451,403 with Prime Factorization

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

13 x 30 x 157 x 451 x 31 = 856056630

Therefore, the lowest common multiple of 390,157,451,403 is 856056630.

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.

390 x 157 x 451 x 403 = 11128736190

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

157 : 1, 157

451 : 1, 11, 41, 451

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,157,451,403, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

157:157

451:11x 41

403:13x 31

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

13 = 13

Therefore, the value for common factors is 13.

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 = 11128736190/(1x13)

LCM = 11128736190/13

LCM = 856056630

Thus, we can understand that the LCM of 390,157,451,403 is 856056630.
