Given numbers are 991,214,343,107

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

The LCM of 991,214,343,107 is 72741382.

Find LCM of 991,214,343,107 with Prime Factorization

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

107 x 991 x 2 x 343 x 1 = 72741382

Therefore, the lowest common multiple of 991,214,343,107 is 72741382.

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 214 x 343 x 107 = 7783327874

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

214 : 1, 2, 107, 214

343 : 1, 7, 49, 343

107 : 1, 107

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,214,343,107, is 1.

Now, the common factors can be found like this.

991:991

214:2x 107

343:7x 7x 7

107:107

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

107 = 107

Therefore, the value for common factors is 107.

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 = 7783327874/(1x107)

LCM = 7783327874/107

LCM = 72741382

Thus, we can understand that the LCM of 991,214,343,107 is 72741382.
