Given numbers are 784,790,163,581

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

The LCM of 784,790,163,581 is 4189660720.

Find LCM of 784,790,163,581 with Prime Factorization

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

2 x 7 x 56 x 395 x 163 x 83 = 4189660720

Therefore, the lowest common multiple of 784,790,163,581 is 4189660720.

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.

784 x 790 x 163 x 581 = 58655250080

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.

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

790 : 1, 2, 5, 10, 79, 158, 395, 790

163 : 1, 163

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,790,163,581, is 1.

Now, the common factors can be found like this.

784:2x 2x 2x 2x 7x 7

790:2x 5x 79

163:163

581:7x 83

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 58655250080/(1x14)

LCM = 58655250080/14

LCM = 4189660720

Thus, we can understand that the LCM of 784,790,163,581 is 4189660720.
