Given numbers are 747,160,642,542

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

The LCM of 747,160,642,542 is 3465721440.

Find LCM of 747,160,642,542 with Prime Factorization

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

2 x 3 x 249 x 80 x 107 x 271 = 3465721440

Therefore, the lowest common multiple of 747,160,642,542 is 3465721440.

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.

747 x 160 x 642 x 542 = 41588657280

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.

747 : 1, 3, 9, 83, 249, 747

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

642 : 1, 2, 3, 6, 107, 214, 321, 642

542 : 1, 2, 271, 542

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,160,642,542, is 1.

Now, the common factors can be found like this.

747:3x 3x 83

160:2x 2x 2x 2x 2x 5

642:2x 3x 107

542:2x 271

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 3 = 12

Therefore, the value for common factors is 12.

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 = 41588657280/(1x12)

LCM = 41588657280/12

LCM = 3465721440

Thus, we can understand that the LCM of 747,160,642,542 is 3465721440.
