Given numbers are 658,342,397,297,780

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

The LCM of 658,342,397,297,780 is 191632781340.

Find LCM of 658,342,397,297,780 with Prime Factorization

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

2 x 3 x 3 x 329 x 19 x 397 x 33 x 130 = 191632781340

Therefore, the lowest common multiple of 658,342,397,297,780 is 191632781340.

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.

658 x 342 x 397 x 297 x 780 = 20696340384720

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

397 : 1, 397

297 : 1, 3, 9, 11, 27, 33, 99, 297

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,342,397,297,780, is 1.

Now, the common factors can be found like this.

658:2x 7x 47

342:2x 3x 3x 19

397:397

297:3x 3x 3x 11

780:2x 2x 3x 5x 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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 20696340384720/(1x108)

LCM = 20696340384720/108

LCM = 191632781340

Thus, we can understand that the LCM of 658,342,397,297,780 is 191632781340.
