Given numbers are 397,478,736,163,208

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

The LCM of 397,478,736,163,208 is 147978008672.

Find LCM of 397,478,736,163,208 with Prime Factorization

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

2 x 2 x 2 x 2 x 397 x 239 x 46 x 163 x 13 = 147978008672

Therefore, the lowest common multiple of 397,478,736,163,208 is 147978008672.

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 478 x 736 x 163 x 208 = 4735296277504

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

478 : 1, 2, 239, 478

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

163 : 1, 163

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,478,736,163,208, is 1.

Now, the common factors can be found like this.

397:397

478:2x 239

736:2x 2x 2x 2x 2x 23

163:163

208:2x 2x 2x 2x 13

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 2x 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 4735296277504/(1x32)

LCM = 4735296277504/32

LCM = 147978008672

Thus, we can understand that the LCM of 397,478,736,163,208 is 147978008672.
