Given numbers are 651,124,217,661

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

The LCM of 651,124,217,661 is 1721244.

Find LCM of 651,124,217,661 with Prime Factorization

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

7 x 31 x 3 x 4 x 1 x 661 = 1721244

Therefore, the lowest common multiple of 651,124,217,661 is 1721244.

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 124 x 217 x 661 = 11578808388

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

124 : 1, 2, 4, 31, 62, 124

217 : 1, 7, 31, 217

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,124,217,661, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

124:2x 2x 31

217:7x 31

661:661

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

7x 31x 31 = 6727

Therefore, the value for common factors is 6727.

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 = 11578808388/(1x6727)

LCM = 11578808388/6727

LCM = 1721244

Thus, we can understand that the LCM of 651,124,217,661 is 1721244.
