Given numbers are 661,488,122,738

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

The LCM of 661,488,122,738 is 119027592.

Find LCM of 661,488,122,738 with Prime Factorization

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

2 x 61 x 661 x 4 x 1 x 369 = 119027592

Therefore, the lowest common multiple of 661,488,122,738 is 119027592.

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 488 x 122 x 738 = 29042732448

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

488 : 1, 2, 4, 8, 61, 122, 244, 488

122 : 1, 2, 61, 122

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,488,122,738, is 1.

Now, the common factors can be found like this.

661:661

488:2x 2x 2x 61

122:2x 61

738:2x 3x 3x 41

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 61 = 244

Therefore, the value for common factors is 244.

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 = 29042732448/(1x244)

LCM = 29042732448/244

LCM = 119027592

Thus, we can understand that the LCM of 661,488,122,738 is 119027592.
