Given numbers are 784,638,679,600

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

The LCM of 784,638,679,600 is 1819448400.

Find LCM of 784,638,679,600 with Prime Factorization

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

2 x 2 x 2 x 7 x 14 x 319 x 97 x 75 = 1819448400

Therefore, the lowest common multiple of 784,638,679,600 is 1819448400.

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 638 x 679 x 600 = 203778220800

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

679 : 1, 7, 97, 679

600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,638,679,600, is 1.

Now, the common factors can be found like this.

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

638:2x 11x 29

679:7x 97

600:2x 2x 2x 3x 5x 5

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 7 = 112

Therefore, the value for common factors is 112.

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 = 203778220800/(1x112)

LCM = 203778220800/112

LCM = 1819448400

Thus, we can understand that the LCM of 784,638,679,600 is 1819448400.
