Given numbers are 161,860,721,203

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

The LCM of 161,860,721,203 is 413580020.

Find LCM of 161,860,721,203 with Prime Factorization

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

7 x 23 x 860 x 103 x 29 = 413580020

Therefore, the lowest common multiple of 161,860,721,203 is 413580020.

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.

161 x 860 x 721 x 203 = 20265420980

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.

161 : 1, 7, 23, 161

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

721 : 1, 7, 103, 721

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,860,721,203, is 1.

Now, the common factors can be found like this.

161:7x 23

860:2x 2x 5x 43

721:7x 103

203:7x 29

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 = 20265420980/(1x49)

LCM = 20265420980/49

LCM = 413580020

Thus, we can understand that the LCM of 161,860,721,203 is 413580020.
