Given numbers are 721,771,707,917

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

The LCM of 721,771,707,917 is 7354993821.

Find LCM of 721,771,707,917 with Prime Factorization

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

7 x 103 x 771 x 101 x 131 = 7354993821

Therefore, the lowest common multiple of 721,771,707,917 is 7354993821.

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.

721 x 771 x 707 x 917 = 360394697229

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.

721 : 1, 7, 103, 721

771 : 1, 3, 257, 771

707 : 1, 7, 101, 707

917 : 1, 7, 131, 917

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,771,707,917, is 1.

Now, the common factors can be found like this.

721:7x 103

771:3x 257

707:7x 101

917:7x 131

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 360394697229/(1x49)

LCM = 360394697229/49

LCM = 7354993821

Thus, we can understand that the LCM of 721,771,707,917 is 7354993821.
