Given numbers are 157,115,618,721

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

The LCM of 157,115,618,721 is 78105930.

Find LCM of 157,115,618,721 with Prime Factorization

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

103 x 157 x 115 x 6 x 7 = 78105930

Therefore, the lowest common multiple of 157,115,618,721 is 78105930.

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.

157 x 115 x 618 x 721 = 8044910790

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.

157 : 1, 157

115 : 1, 5, 23, 115

618 : 1, 2, 3, 6, 103, 206, 309, 618

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,115,618,721, is 1.

Now, the common factors can be found like this.

157:157

115:5x 23

618:2x 3x 103

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.

103 = 103

Therefore, the value for common factors is 103.

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 = 8044910790/(1x103)

LCM = 8044910790/103

LCM = 78105930

Thus, we can understand that the LCM of 157,115,618,721 is 78105930.
