Given numbers are 991,129,564,978

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

The LCM of 991,129,564,978 is 3917498316.

Find LCM of 991,129,564,978 with Prime Factorization

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

2 x 3 x 991 x 43 x 94 x 163 = 3917498316

Therefore, the lowest common multiple of 991,129,564,978 is 3917498316.

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 129 x 564 x 978 = 70514969688

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

129 : 1, 3, 43, 129

564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564

978 : 1, 2, 3, 6, 163, 326, 489, 978

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,129,564,978, is 1.

Now, the common factors can be found like this.

991:991

129:3x 43

564:2x 2x 3x 47

978:2x 3x 163

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 70514969688/(1x18)

LCM = 70514969688/18

LCM = 3917498316

Thus, we can understand that the LCM of 991,129,564,978 is 3917498316.
