Given numbers are 688,961,708,911

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

The LCM of 688,961,708,911 is 106611356496.

Find LCM of 688,961,708,911 with Prime Factorization

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

2 x 2 x 172 x 961 x 177 x 911 = 106611356496

Therefore, the lowest common multiple of 688,961,708,911 is 106611356496.

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 961 x 708 x 911 = 426445425984

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

961 : 1, 31, 961

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

911 : 1, 911

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,961,708,911, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

961:31x 31

708:2x 2x 3x 59

911:911

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 = 426445425984/(1x4)

LCM = 426445425984/4

LCM = 106611356496

Thus, we can understand that the LCM of 688,961,708,911 is 106611356496.
