Given numbers are 397,565,565,974

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

The LCM of 397,565,565,974 is 218473070.

Find LCM of 397,565,565,974 with Prime Factorization

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

5 x 113 x 397 x 1 x 1 x 974 = 218473070

Therefore, the lowest common multiple of 397,565,565,974 is 218473070.

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 565 x 565 x 974 = 123437284550

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

565 : 1, 5, 113, 565

565 : 1, 5, 113, 565

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,565,565,974, is 1.

Now, the common factors can be found like this.

397:397

565:5x 113

565:5x 113

974:2x 487

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

5x 113 = 565

Therefore, the value for common factors is 565.

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 = 123437284550/(1x565)

LCM = 123437284550/565

LCM = 218473070

Thus, we can understand that the LCM of 397,565,565,974 is 218473070.
