Given numbers are 661,637,341,661

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

The LCM of 661,637,341,661 is 143580437.

Find LCM of 661,637,341,661 with Prime Factorization

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

661 x 1 x 637 x 341 x 1 = 143580437

Therefore, the lowest common multiple of 661,637,341,661 is 143580437.

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.

661 x 637 x 341 x 661 = 94906668857

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.

661 : 1, 661

637 : 1, 7, 13, 49, 91, 637

341 : 1, 11, 31, 341

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,637,341,661, is 1.

Now, the common factors can be found like this.

661:661

637:7x 7x 13

341:11x 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.

661 = 661

Therefore, the value for common factors is 661.

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 = 94906668857/(1x661)

LCM = 94906668857/661

LCM = 143580437

Thus, we can understand that the LCM of 661,637,341,661 is 143580437.
