Given numbers are 991,407,178,351,247

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

The LCM of 991,407,178,351,247 is 478794092634.

Find LCM of 991,407,178,351,247 with Prime Factorization

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

13 x 991 x 407 x 178 x 27 x 19 = 478794092634

Therefore, the lowest common multiple of 991,407,178,351,247 is 478794092634.

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.

991 x 407 x 178 x 351 x 247 = 6224323204242

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.

991 : 1, 991

407 : 1, 11, 37, 407

178 : 1, 2, 89, 178

351 : 1, 3, 9, 13, 27, 39, 117, 351

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,407,178,351,247, is 1.

Now, the common factors can be found like this.

991:991

407:11x 37

178:2x 89

351:3x 3x 3x 13

247:13x 19

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

13 = 13

Therefore, the value for common factors is 13.

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 = 6224323204242/(1x13)

LCM = 6224323204242/13

LCM = 478794092634

Thus, we can understand that the LCM of 991,407,178,351,247 is 478794092634.
