Given numbers are 688,159,118,902

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

The LCM of 688,159,118,902 is 2910811728.

Find LCM of 688,159,118,902 with Prime Factorization

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

2 x 344 x 159 x 59 x 451 = 2910811728

Therefore, the lowest common multiple of 688,159,118,902 is 2910811728.

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 159 x 118 x 902 = 11643246912

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

159 : 1, 3, 53, 159

118 : 1, 2, 59, 118

902 : 1, 2, 11, 22, 41, 82, 451, 902

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,159,118,902, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

159:3x 53

118:2x 59

902:2x 11x 41

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 = 11643246912/(1x4)

LCM = 11643246912/4

LCM = 2910811728

Thus, we can understand that the LCM of 688,159,118,902 is 2910811728.
