Given numbers are 991,437,989,782

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

The LCM of 991,437,989,782 is 633143954.

Find LCM of 991,437,989,782 with Prime Factorization

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

23 x 991 x 19 x 43 x 34 = 633143954

Therefore, the lowest common multiple of 991,437,989,782 is 633143954.

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 437 x 989 x 782 = 334933151666

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

437 : 1, 19, 23, 437

989 : 1, 23, 43, 989

782 : 1, 2, 17, 23, 34, 46, 391, 782

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,437,989,782, is 1.

Now, the common factors can be found like this.

991:991

437:19x 23

989:23x 43

782:2x 17x 23

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

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 334933151666/(1x529)

LCM = 334933151666/529

LCM = 633143954

Thus, we can understand that the LCM of 991,437,989,782 is 633143954.
