Given numbers are 538,124,651,991

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

The LCM of 538,124,651,991 is 694171716.

Find LCM of 538,124,651,991 with Prime Factorization

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

2 x 31 x 269 x 2 x 21 x 991 = 694171716

Therefore, the lowest common multiple of 538,124,651,991 is 694171716.

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.

538 x 124 x 651 x 991 = 43038646392

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.

538 : 1, 2, 269, 538

124 : 1, 2, 4, 31, 62, 124

651 : 1, 3, 7, 21, 31, 93, 217, 651

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,124,651,991, is 1.

Now, the common factors can be found like this.

538:2x 269

124:2x 2x 31

651:3x 7x 31

991:991

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

2x 31 = 62

Therefore, the value for common factors is 62.

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 = 43038646392/(1x62)

LCM = 43038646392/62

LCM = 694171716

Thus, we can understand that the LCM of 538,124,651,991 is 694171716.
