Given numbers are 721,692,406,293

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

The LCM of 721,692,406,293 is 4239425204.

Find LCM of 721,692,406,293 with Prime Factorization

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

2 x 7 x 103 x 346 x 29 x 293 = 4239425204

Therefore, the lowest common multiple of 721,692,406,293 is 4239425204.

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 692 x 406 x 293 = 59351952856

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

692 : 1, 2, 4, 173, 346, 692

406 : 1, 2, 7, 14, 29, 58, 203, 406

293 : 1, 293

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,692,406,293, is 1.

Now, the common factors can be found like this.

721:7x 103

692:2x 2x 173

406:2x 7x 29

293:293

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 59351952856/(1x14)

LCM = 59351952856/14

LCM = 4239425204

Thus, we can understand that the LCM of 721,692,406,293 is 4239425204.
