Given numbers are 722,652,978,395

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

The LCM of 722,652,978,395 is 278915820.

Find LCM of 722,652,978,395 with Prime Factorization

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

2 x 163 x 361 x 2 x 3 x 395 = 278915820

Therefore, the lowest common multiple of 722,652,978,395 is 278915820.

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.

722 x 652 x 978 x 395 = 181853114640

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.

722 : 1, 2, 19, 38, 361, 722

652 : 1, 2, 4, 163, 326, 652

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

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,652,978,395, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

652:2x 2x 163

978:2x 3x 163

395:5x 79

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 163 = 652

Therefore, the value for common factors is 652.

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 = 181853114640/(1x652)

LCM = 181853114640/652

LCM = 278915820

Thus, we can understand that the LCM of 722,652,978,395 is 278915820.
