Given numbers are 669,734,142,291

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

The LCM of 669,734,142,291 is 3381833802.

Find LCM of 669,734,142,291 with Prime Factorization

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

2 x 3 x 223 x 367 x 71 x 97 = 3381833802

Therefore, the lowest common multiple of 669,734,142,291 is 3381833802.

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.

669 x 734 x 142 x 291 = 20291002812

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.

669 : 1, 3, 223, 669

734 : 1, 2, 367, 734

142 : 1, 2, 71, 142

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,734,142,291, is 1.

Now, the common factors can be found like this.

669:3x 223

734:2x 367

142:2x 71

291:3x 97

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 20291002812/(1x6)

LCM = 20291002812/6

LCM = 3381833802

Thus, we can understand that the LCM of 669,734,142,291 is 3381833802.
