Given numbers are 721,747,138,516

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

The LCM of 721,747,138,516 is 2130650172.

Find LCM of 721,747,138,516 with Prime Factorization

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

2 x 3 x 721 x 249 x 23 x 86 = 2130650172

Therefore, the lowest common multiple of 721,747,138,516 is 2130650172.

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 747 x 138 x 516 = 38351703096

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

747 : 1, 3, 9, 83, 249, 747

138 : 1, 2, 3, 6, 23, 46, 69, 138

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,747,138,516, is 1.

Now, the common factors can be found like this.

721:7x 103

747:3x 3x 83

138:2x 3x 23

516:2x 2x 3x 43

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 38351703096/(1x18)

LCM = 38351703096/18

LCM = 2130650172

Thus, we can understand that the LCM of 721,747,138,516 is 2130650172.
