Given numbers are 397,671,473,748

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

The LCM of 397,671,473,748 is 778915588.

Find LCM of 397,671,473,748 with Prime Factorization

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

11 x 397 x 61 x 43 x 68 = 778915588

Therefore, the lowest common multiple of 397,671,473,748 is 778915588.

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 671 x 473 x 748 = 94248786148

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

671 : 1, 11, 61, 671

473 : 1, 11, 43, 473

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,671,473,748, is 1.

Now, the common factors can be found like this.

397:397

671:11x 61

473:11x 43

748:2x 2x 11x 17

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 94248786148/(1x121)

LCM = 94248786148/121

LCM = 778915588

Thus, we can understand that the LCM of 397,671,473,748 is 778915588.
