Given numbers are 197,138,638,517

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

The LCM of 197,138,638,517 is 407599698.

Find LCM of 197,138,638,517 with Prime Factorization

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

2 x 11 x 197 x 69 x 29 x 47 = 407599698

Therefore, the lowest common multiple of 197,138,638,517 is 407599698.

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.

197 x 138 x 638 x 517 = 8967193356

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.

197 : 1, 197

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

517 : 1, 11, 47, 517

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,138,638,517, is 1.

Now, the common factors can be found like this.

197:197

138:2x 3x 23

638:2x 11x 29

517:11x 47

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 8967193356/(1x22)

LCM = 8967193356/22

LCM = 407599698

Thus, we can understand that the LCM of 197,138,638,517 is 407599698.
