Given numbers are 493,194,420,136

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

The LCM of 493,194,420,136 is 40169640.

Find LCM of 493,194,420,136 with Prime Factorization

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

2 x 2 x 17 x 29 x 97 x 105 x 2 = 40169640

Therefore, the lowest common multiple of 493,194,420,136 is 40169640.

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.

493 x 194 x 420 x 136 = 5463071040

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.

493 : 1, 17, 29, 493

194 : 1, 2, 97, 194

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

136 : 1, 2, 4, 8, 17, 34, 68, 136

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,194,420,136, is 1.

Now, the common factors can be found like this.

493:17x 29

194:2x 97

420:2x 2x 3x 5x 7

136:2x 2x 2x 17

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 17 = 136

Therefore, the value for common factors is 136.

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 = 5463071040/(1x136)

LCM = 5463071040/136

LCM = 40169640

Thus, we can understand that the LCM of 493,194,420,136 is 40169640.
