Given numbers are 651,997,217

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

The LCM of 651,997,217 is 649047.

Find LCM of 651,997,217 with Prime Factorization

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

7 x 31 x 3 x 997 x 1 = 649047

Therefore, the lowest common multiple of 651,997,217 is 649047.

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.

651 x 997 x 217 = 140843199

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.

651 : 1, 3, 7, 21, 31, 93, 217, 651

997 : 1, 997

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,997,217, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

997:997

217:7x 31

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

7x 31 = 217

Therefore, the value for common factors is 217.

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 = 140843199/(1x217)

LCM = 140843199/217

LCM = 649047

Thus, we can understand that the LCM of 651,997,217 is 649047.

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

• LCM of 907, 307, 153
• LCM of 475, 321, 528
