Given numbers are 245,856,122,107,138

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

The LCM of 245,856,122,107,138 is 882711480.

Find LCM of 245,856,122,107,138 with Prime Factorization

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

2 x 107 x 245 x 4 x 61 x 1 x 69 = 882711480

Therefore, the lowest common multiple of 245,856,122,107,138 is 882711480.

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.

245 x 856 x 122 x 107 x 138 = 377800513440

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.

245 : 1, 5, 7, 35, 49, 245

856 : 1, 2, 4, 8, 107, 214, 428, 856

122 : 1, 2, 61, 122

107 : 1, 107

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,856,122,107,138, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

856:2x 2x 2x 107

122:2x 61

107:107

138:2x 3x 23

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 107 = 428

Therefore, the value for common factors is 428.

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 = 377800513440/(1x428)

LCM = 377800513440/428

LCM = 882711480

Thus, we can understand that the LCM of 245,856,122,107,138 is 882711480.
