Given numbers are 782,978,381,281

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

The LCM of 782,978,381,281 is 13646637426.

Find LCM of 782,978,381,281 with Prime Factorization

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

2 x 3 x 391 x 163 x 127 x 281 = 13646637426

Therefore, the lowest common multiple of 782,978,381,281 is 13646637426.

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.

782 x 978 x 381 x 281 = 81879824556

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

978 : 1, 2, 3, 6, 163, 326, 489, 978

381 : 1, 3, 127, 381

281 : 1, 281

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,978,381,281, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

978:2x 3x 163

381:3x 127

281:281

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 81879824556/(1x6)

LCM = 81879824556/6

LCM = 13646637426

Thus, we can understand that the LCM of 782,978,381,281 is 13646637426.
