Given numbers are 251,930,432,690

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

The LCM of 251,930,432,690 is 386560080.

Find LCM of 251,930,432,690 with Prime Factorization

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

2 x 3 x 5 x 251 x 31 x 72 x 23 = 386560080

Therefore, the lowest common multiple of 251,930,432,690 is 386560080.

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.

251 x 930 x 432 x 690 = 69580814400

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.

251 : 1, 251

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,930,432,690, is 1.

Now, the common factors can be found like this.

251:251

930:2x 3x 5x 31

432:2x 2x 2x 2x 3x 3x 3

690:2x 3x 5x 23

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

2x 2x 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 69580814400/(1x180)

LCM = 69580814400/180

LCM = 386560080

Thus, we can understand that the LCM of 251,930,432,690 is 386560080.
