Given numbers are 786,978,393,217,284

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

The LCM of 786,978,393,217,284 is 3947828052.

Find LCM of 786,978,393,217,284 with Prime Factorization

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

2 x 3 x 131 x 1 x 163 x 1 x 217 x 142 = 3947828052

Therefore, the lowest common multiple of 786,978,393,217,284 is 3947828052.

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.

786 x 978 x 393 x 217 x 284 = 18617957093232

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

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

393 : 1, 3, 131, 393

217 : 1, 7, 31, 217

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,978,393,217,284, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

978:2x 3x 163

393:3x 131

217:7x 31

284:2x 2x 71

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 131 = 4716

Therefore, the value for common factors is 4716.

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 = 18617957093232/(1x4716)

LCM = 18617957093232/4716

LCM = 3947828052

Thus, we can understand that the LCM of 786,978,393,217,284 is 3947828052.
