Given numbers are 138,557,755,970

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

The LCM of 138,557,755,970 is 5629281510.

Find LCM of 138,557,755,970 with Prime Factorization

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

2 x 5 x 69 x 557 x 151 x 97 = 5629281510

Therefore, the lowest common multiple of 138,557,755,970 is 5629281510.

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.

138 x 557 x 755 x 970 = 56292815100

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

557 : 1, 557

755 : 1, 5, 151, 755

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,557,755,970, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

557:557

755:5x 151

970:2x 5x 97

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 56292815100/(1x10)

LCM = 56292815100/10

LCM = 5629281510

Thus, we can understand that the LCM of 138,557,755,970 is 5629281510.
