Given numbers are 688,678,962,858

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

The LCM of 688,678,962,858 is 1234030512.

Find LCM of 688,678,962,858 with Prime Factorization

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

2 x 3 x 13 x 344 x 113 x 37 x 11 = 1234030512

Therefore, the lowest common multiple of 688,678,962,858 is 1234030512.

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.

688 x 678 x 962 x 858 = 385017519744

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

678 : 1, 2, 3, 6, 113, 226, 339, 678

962 : 1, 2, 13, 26, 37, 74, 481, 962

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,678,962,858, is 2.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

678:2x 3x 113

962:2x 13x 37

858:2x 3x 11x 13

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 3x 13 = 156

Therefore, the value for common factors is 156.

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 = 385017519744/(2x156)

LCM = 385017519744/312

LCM = 1234030512

Thus, we can understand that the LCM of 688,678,962,858 is 1234030512.
