Given numbers are 783,758,676,421

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

The LCM of 783,758,676,421 is 84455855172.

Find LCM of 783,758,676,421 with Prime Factorization

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

2 x 783 x 379 x 338 x 421 = 84455855172

Therefore, the lowest common multiple of 783,758,676,421 is 84455855172.

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.

783 x 758 x 676 x 421 = 168911710344

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.

783 : 1, 3, 9, 27, 29, 87, 261, 783

758 : 1, 2, 379, 758

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,758,676,421, is 1.

Now, the common factors can be found like this.

783:3x 3x 3x 29

758:2x 379

676:2x 2x 13x 13

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 168911710344/(1x2)

LCM = 168911710344/2

LCM = 84455855172

Thus, we can understand that the LCM of 783,758,676,421 is 84455855172.
