Given numbers are 784,763,812,626,642

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

The LCM of 784,763,812,626,642 is 248994599952.

Find LCM of 784,763,812,626,642 with Prime Factorization

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

2 x 2 x 7 x 28 x 109 x 29 x 313 x 321 = 248994599952

Therefore, the lowest common multiple of 784,763,812,626,642 is 248994599952.

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 763 x 812 x 626 x 642 = 195211766362368

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

763 : 1, 7, 109, 763

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

626 : 1, 2, 313, 626

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,763,812,626,642, is 1.

Now, the common factors can be found like this.

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

763:7x 109

812:2x 2x 7x 29

626:2x 313

642:2x 3x 107

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 2x 7x 7 = 784

Therefore, the value for common factors is 784.

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 = 195211766362368/(1x784)

LCM = 195211766362368/784

LCM = 248994599952

Thus, we can understand that the LCM of 784,763,812,626,642 is 248994599952.
