Given numbers are 721,389,221,168,141

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

The LCM of 721,389,221,168,141 is 69917556072.

Find LCM of 721,389,221,168,141 with Prime Factorization

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

3 x 7 x 103 x 389 x 221 x 8 x 47 = 69917556072

Therefore, the lowest common multiple of 721,389,221,168,141 is 69917556072.

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 389 x 221 x 168 x 141 = 1468268677512

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

389 : 1, 389

221 : 1, 13, 17, 221

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

141 : 1, 3, 47, 141

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,389,221,168,141, is 1.

Now, the common factors can be found like this.

721:7x 103

389:389

221:13x 17

168:2x 2x 2x 3x 7

141:3x 47

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 1468268677512/(1x21)

LCM = 1468268677512/21

LCM = 69917556072

Thus, we can understand that the LCM of 721,389,221,168,141 is 69917556072.
