Given numbers are 424,991,447,781,636

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

The LCM of 424,991,447,781,636 is 146689175688.

Find LCM of 424,991,447,781,636 with Prime Factorization

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

2 x 2 x 3 x 53 x 2 x 991 x 149 x 781 x 1 = 146689175688

Therefore, the lowest common multiple of 424,991,447,781,636 is 146689175688.

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.

424 x 991 x 447 x 781 x 636 = 93294315737568

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.

424 : 1, 2, 4, 8, 53, 106, 212, 424

991 : 1, 991

447 : 1, 3, 149, 447

781 : 1, 11, 71, 781

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,991,447,781,636, is 1.

Now, the common factors can be found like this.

424:2x 2x 2x 53

991:991

447:3x 149

781:11x 71

636:2x 2x 3x 53

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 3x 53 = 636

Therefore, the value for common factors is 636.

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 = 93294315737568/(1x636)

LCM = 93294315737568/636

LCM = 146689175688

Thus, we can understand that the LCM of 424,991,447,781,636 is 146689175688.
