Given numbers are 397,956,690

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

The LCM of 397,956,690 is 130938540.

Find LCM of 397,956,690 with Prime Factorization

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

2 x 397 x 478 x 345 = 130938540

Therefore, the lowest common multiple of 397,956,690 is 130938540.

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.

397 x 956 x 690 = 261877080

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.

397 : 1, 397

956 : 1, 2, 4, 239, 478, 956

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 397,956,690, is 1.

Now, the common factors can be found like this.

397:397

956:2x 2x 239

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 261877080/(1x2)

LCM = 261877080/2

LCM = 130938540

Thus, we can understand that the LCM of 397,956,690 is 130938540.
