Given numbers are 131,946,688,721

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

The LCM of 131,946,688,721 is 714805168.

Find LCM of 131,946,688,721 with Prime Factorization

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

2 x 43 x 131 x 11 x 8 x 721 = 714805168

Therefore, the lowest common multiple of 131,946,688,721 is 714805168.

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.

131 x 946 x 688 x 721 = 61473244448

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.

131 : 1, 131

946 : 1, 2, 11, 22, 43, 86, 473, 946

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

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,946,688,721, is 1.

Now, the common factors can be found like this.

131:131

946:2x 11x 43

688:2x 2x 2x 2x 43

721:7x 103

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

2x 43 = 86

Therefore, the value for common factors is 86.

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 = 61473244448/(1x86)

LCM = 61473244448/86

LCM = 714805168

Thus, we can understand that the LCM of 131,946,688,721 is 714805168.
