Given numbers are 532,954,618,420

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

The LCM of 532,954,618,420 is 130688460.

Find LCM of 532,954,618,420 with Prime Factorization

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

2 x 2 x 3 x 7 x 19 x 159 x 103 x 5 = 130688460

Therefore, the lowest common multiple of 532,954,618,420 is 130688460.

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.

532 x 954 x 618 x 420 = 131733967680

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.

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954

618 : 1, 2, 3, 6, 103, 206, 309, 618

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 532,954,618,420, is 2.

Now, the common factors can be found like this.

532:2x 2x 7x 19

954:2x 3x 3x 53

618:2x 3x 103

420:2x 2x 3x 5x 7

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

2x 2x 2x 3x 3x 7 = 504

Therefore, the value for common factors is 504.

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 = 131733967680/(2x504)

LCM = 131733967680/1008

LCM = 130688460

Thus, we can understand that the LCM of 532,954,618,420 is 130688460.
