Given numbers are 662,728,647

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

The LCM of 662,728,647 is 155906296.

Find LCM of 662,728,647 with Prime Factorization

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

2 x 331 x 364 x 647 = 155906296

Therefore, the lowest common multiple of 662,728,647 is 155906296.

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.

662 x 728 x 647 = 311812592

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.

662 : 1, 2, 331, 662

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,728,647, is 1.

Now, the common factors can be found like this.

662:2x 331

728:2x 2x 2x 7x 13

647:647

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

2 = 2

Therefore, the value for common factors is 2.

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 = 311812592/(1x2)

LCM = 311812592/2

LCM = 155906296

Thus, we can understand that the LCM of 662,728,647 is 155906296.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 405, 371, 126
