Given numbers are 764,335,902,390,721

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

The LCM of 764,335,902,390,721 is 3245746363860.

Find LCM of 764,335,902,390,721 with Prime Factorization

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

2 x 5 x 382 x 67 x 451 x 39 x 721 = 3245746363860

Therefore, the lowest common multiple of 764,335,902,390,721 is 3245746363860.

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.

764 x 335 x 902 x 390 x 721 = 64914927277200

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.

764 : 1, 2, 4, 191, 382, 764

335 : 1, 5, 67, 335

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

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,335,902,390,721, is 1.

Now, the common factors can be found like this.

764:2x 2x 191

335:5x 67

902:2x 11x 41

390:2x 3x 5x 13

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 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 64914927277200/(1x20)

LCM = 64914927277200/20

LCM = 3245746363860

Thus, we can understand that the LCM of 764,335,902,390,721 is 3245746363860.
