Given numbers are 426,997,438,173

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

The LCM of 426,997,438,173 is 5363814138.

Find LCM of 426,997,438,173 with Prime Factorization

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

2 x 3 x 71 x 997 x 73 x 173 = 5363814138

Therefore, the lowest common multiple of 426,997,438,173 is 5363814138.

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.

426 x 997 x 438 x 173 = 32182884828

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

997 : 1, 997

438 : 1, 2, 3, 6, 73, 146, 219, 438

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,997,438,173, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

997:997

438:2x 3x 73

173:173

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 = 32182884828/(1x6)

LCM = 32182884828/6

LCM = 5363814138

Thus, we can understand that the LCM of 426,997,438,173 is 5363814138.
