Given numbers are 7,425,399,742

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

The LCM of 7,425,399,742 is 17974950.

Find LCM of 7,425,399,742 with Prime Factorization

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

7 x 1 x 425 x 57 x 106 = 17974950

Therefore, the lowest common multiple of 7,425,399,742 is 17974950.

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.

7 x 425 x 399 x 742 = 880772550

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.

7 : 1, 7

425 : 1, 5, 17, 25, 85, 425

399 : 1, 3, 7, 19, 21, 57, 133, 399

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,425,399,742, is 1.

Now, the common factors can be found like this.

7:7

425:5x 5x 17

399:3x 7x 19

742:2x 7x 53

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 880772550/(1x49)

LCM = 880772550/49

LCM = 17974950

Thus, we can understand that the LCM of 7,425,399,742 is 17974950.
