Given numbers are 531,478,338,661

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

The LCM of 531,478,338,661 is 28353754962.

Find LCM of 531,478,338,661 with Prime Factorization

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

2 x 531 x 239 x 169 x 661 = 28353754962

Therefore, the lowest common multiple of 531,478,338,661 is 28353754962.

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.

531 x 478 x 338 x 661 = 56707509924

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.

531 : 1, 3, 9, 59, 177, 531

478 : 1, 2, 239, 478

338 : 1, 2, 13, 26, 169, 338

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,478,338,661, is 1.

Now, the common factors can be found like this.

531:3x 3x 59

478:2x 239

338:2x 13x 13

661:661

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 = 56707509924/(1x2)

LCM = 56707509924/2

LCM = 28353754962

Thus, we can understand that the LCM of 531,478,338,661 is 28353754962.
