Given numbers are 688,889,678,542

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

The LCM of 688,889,678,542 is 56190020208.

Find LCM of 688,889,678,542 with Prime Factorization

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

2 x 344 x 889 x 339 x 271 = 56190020208

Therefore, the lowest common multiple of 688,889,678,542 is 56190020208.

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 889 x 678 x 542 = 224760080832

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

889 : 1, 7, 127, 889

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

542 : 1, 2, 271, 542

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,889,678,542, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

889:7x 127

678:2x 3x 113

542:2x 271

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 224760080832/(1x4)

LCM = 224760080832/4

LCM = 56190020208

Thus, we can understand that the LCM of 688,889,678,542 is 56190020208.
